I have previously struggled to correct an incorrect brand on a product page through Seller Support so hope I can get somewhere by posting this here.

There isn't any question that this is a Nintendo brand product and 'REIOCUSHI' is an irrelevant brand which this page should never have been changed to in the first place.

To make matters worse, the brand 'REIOCUSHI' is also gated.

It's very frustrating as a seller that a listing cannot be create due to the fact there is a gated brand on it which is a brand which it never should have been changed to in the first place!

Can somebody within Amazon take a look at this and correct the page's brand name?

Yes, I am fairly new to the game and have not had a lot of sales in the past 4 months. However, I, in November(recently) received a claim for a product purchased in August and shipped literally 3 days later that the item wasn't received. I reached out to the buyer, reassuring them by referring to the courier's website with tracking info, which includes a picture of the parcel very much being delivered to their door with somebody present receiving the very parcel I had packed and labelled with my very own hands.

All it took was one claim to Amazon, and funds have been approved to be taken OUT of my account. When I went to claim and appeal this, amazon nonchalantly advises me 'If you have not shipped the order, we recommend that you do not ship it, because the customer has been refunded'. However, I have appealed and would be really surprised for it to not be in my favour.

Anyways, to answer your question, when I reached back to the buyer with my response of all tracking info and proof as well as a picture of somebody receiving the item(the customer I presume), they seemed satisfied enough and it said in green 'the customer is satisfied with your response that the enquiry is dealt with'(or something along those lines), but still funds are pending to leave my account :)))

It's difficult to be exact since your figures are in Euros and i don't know to what extent the rates may differ from the UK.

Generally though the original DST was covered by Amazon increasing the main referral fee from 15% to 15.3%. I don't recall there being any increase to FBA fees.

With the latest change the main referral fee has reduced back to 15% which is good for FBM sellers (and FBA sellers), but the other FBA fees are now in scope which means often there is a slight increase to the total fees for FBA sellers - as you've found.

As to your referral fee always being 3.30, that's 15% rather than 15.3% so in the UK that would match with the lowering of the referral fee.

I've listed a Star Wars toy which has the descriptive name 'Supreme leader' in the title and have now received a Suspected Intellectual Property Violation for violating the Supreme brand's trademarks.

There's not even an appeal option in Account health, just an 'Edit' button for the listing (which Amazon don't allow me to edit even if I wanted to.)

Is there any hope/way to deal with this or should I just not even bother and delete the listing?

I use LinkMyBooks and give it a 10/10

It does everything you need it to do, correctly mapping tax rates and breaking down everything by fee type etc.

And you know there won't be any discrepancies as the settlement is matched to the bank transfer.
