HitBTC Keeps Delaying My 2FA Renewal Despite Providing All Required Documents

HitBTC seems to be completely unreliable. I've been strung along for weeks with customer support. My username and password are valid. My 2FA token has expired. I haven't logged in for ages, so I had to connect with customer support to renew my 2FA. They've asked for banking information, transaction history, my full passport, a selfie picture with their most recent email legibly on screen behind me, utility bills and statements to my house for proof of address, etc. I have provided EVERY SINGLE THING they've asked for. Yet they continue to ask for more. Worse, they ask for things one email at a time, so it takes weeks on end to "verify" yourself because they string the next ask a few days behind the previous one. Absolutely horrid. At this point I want access so I can remove anything/everything I might still have with them and go elsewhere. Rubbish service.
