Anyone being hung up on as a customer on the phone? + I was given email address before that, but does it work?

Anyone being hung up on by Amazon as a customer? Sometimes my phonecalls get cut off, so I don’t know if it’s Amz, or if my line is bad.

Before I was cut off, I was given an email address, but does it work - anyone has ever tried it?
Because me, I’m not getting any reply nor automatic acknowledgement so-far.

Then I found I’d been given this one at least a year ago, but never came around to using it:

customer-attachment-requests@amazon.co.uk

And here’s yet 2 more addresses I tried as a customer, but replying to a post-phonecall email I received (which doesn’t seem to be a no-reply one) which had both addresses in, but again no sign of either being received or not:

cs-reply@amazon.co.uk
And
cs-reply+A313Z76XJBSY1U@amazon.co.uk
(this one is probably referring to my particular enquiry).

I emailed the top 2 yesterday mid-afternoon, and the cs-ones on the 19th - how long do you think I need to wait to know if there’s going to be a reply or not?

I’m upset with a complaint that I want to resolve - if now it’s become as hard to get anywhere as a buyer, as it is as a seller, how on earth do I proceed, any tips?..

Many thanks.
