it's never happened to me personally but it's not unheard of. i can't find any threads about specific cases on coinbase, but it took binance a few weeks to sort out a similar situation.
how many times have you followed up on your ticket? the only time i had an issue that required customer support, coinbase replied with ~3 irrelevant boilerplate emails before a competent human finally addressed my problem. you need to keep pushing them, otherwise it'll fall through the cracks.
also, post your issue and ticket # on https://www.reddit.com/r/coinbase ......that tends to get their attention.
Thanks! I will post also in reddit!.
I understand that you sent BTC from Coinbase to some other wallet (service) and they sent them back to you at the same address in Coinbase?
If this happened, then you have nothing to worry about. Coinbase is a very solid exchange and if it wasn't some suspicious service (the one that gave you back BTC) then you will definitely get your BTC back.
Yes Sir. I sent from CoinBase to other wallet (investment platform), I didn´t accept the terms and conditions so they sent them back to the same address.
I will post in reddit and email again!
Thanks for your answer!! <3
