posting here as not sure where else to pass on my experience.

Recently had a chargeback dispute with Onbuy as a seller, 8 weeks later was told that the bank did not accept the evidence and I would therefore be charged the full amount and pay a £14 admin charge to Onbuy, and of course the customer has kept the delivery This was despite not only a fully tracked service showing delivery with a photo of the parcel in the doorway next to the customer, but also a message from the customer confirming receipt of the parcel. It could not be more clearcut, but onbuy would not accept it, just keep blaiming the bank. When I asked for an escalation route to complain they say there is not one, it is in effect a final decision, just keep blaiming the bank.

Sorry to rant, but it is sooo hard being a seller on these resale channels, and examples like this just destroy me. Not even about the £50 lost, its the fact that a customer is scamming everyone, banks and onbuy just accept it and pass the cost onto the seller. and we as sellers should not let the channels get away with a policy if we feel it is unfair.

I guess it also shows the grass is not always greener outside of Amazon. Even Amazon would not do this to me. At least Amazon drives good traffic, onbuy does not even do that,

apologies, going for a glass of wine now,

At least it's not just is then. Ever since it was introduced it seems to be very touch and go as to whether it works. One of the other forum members had a line to the Amazon person in charge of it and reported back more than once that it wasn't working, to which the person had been unaware and 'switched it back on' again.

I guess we'll just have to go without. So frustrating that things can't just work and stay working. There's also the fact that it's never worked for consignments of more than 50 sku's (49 seems to be the tipping point), but obviously that's never reported - it just took us a whole load of trial and error to figure it out.

Hello,

Since 10/05/2026, I’ve been experiencing a completely new error on Amazon that I’ve never seen before.

When adding a card (credit or debit — I tested multiple cards issued in the UK), the normal process should redirect you to MFA/3D Secure verification, where you confirm the payment in your banking app or via OTP.

However, because of this bug, that step is skipped entirely.

Instead, I immediately receive a red error banner saying:

“Your card could not be verified. Please try again.”

The strange part is that after clicking “Verify” around 50–100 times, the error randomly stopped on the UK and DE marketplaces, and I managed to get those verified.

However, the issue still continues on other EU marketplaces, meaning I’m unable to fully verify my account.

I’ve already:

* Created multiple support cases

* Spoken to representatives via live chat

* Contacted support by phone

Unfortunately, I still haven’t received any real resolution.

Most responses I receive are generic copy-pasted troubleshooting steps that do not address the actual technical issue. Even after explaining that this appears to be a backend verification bug, I keep getting the same scripted replies or being told nothing can be done.

At this point:

* The system appears broken

* Account setup is impossible

* Getting meaningful technical support feels impossible as well

Cases are often closed quickly without proper investigation, sometimes before I even receive a chance to respond.

I’m posting this in hopes that Amazon representatives or technical staff will actually look into the issue.

Please do not suggest:

* “Use another card”

* “Complete MFA”

The problem is that MFA never appears because the verification process fails before reaching that stage.

This issue happens with both debit and credit cards, and as mentioned earlier, after dozens of retries the verification randomly succeeded on DE and UK marketplaces, which strongly suggests this is a platform bug.

I’m extremely frustrated.

Why does Amazon’s verification system have to be so complicated and unreliable compared to platforms like eBay?

Please fix your system, Amazon.

Hi dunsterville34,

You're post seems to have been curtailed and I'm interested to learn how it ends...

As for upset buyers leaving feedback, I have had over 1000 FBs and only 9 are Neutral or Negative... but haven't had ANY since 4/4/26... and as I've reported elsewhere my Lifetime feedbacks are decreasing, which shouldn't happen without Amazon interference

Oh, and I noted a Seller the other day who only had 50% on feedback - but I'm sure Amazon are helping them improve their score...

All Best

Brian

I think this deserve a more open discussion and to show other sellers what is happening.

It transpires that the "AI" Amazon system could not determine if

£0 free delivery

£1 for 2 day

£2 for 1 day

was a fair price - because we did not have the weight and dimensions of the items declared to amazon

therefore amazon could not determine if those rates were fair.

we were then told we have to set the weight and dims on the 92 asin we have on that template.

(I have agreed to do this - but I should have to!)

this is absolutely ridiculous.

if we as a seller had an "exceptional" delivery fee (let's say £25 or £50) - then yes fair enough ask us to show the weight/dimensions of the item (perhaps like flat-pack furniture or a 1 ton car jack)

can I take exception to

"unaffected in the meantime"

no "meantime" there is nothing wrong with our delivery prices - I am sure you didnt mean it like that but it sounds as we are still being scrutinised over this ridiculous situation.
