Just be aware of the covid19 situation have you looked into another option?
After a lengthy process I would just call it quits for them, try looking into cashapp for smaller increments since most of these crypto exchanges are based on no live chat or live phone number to talk with a real person.
I have personally gone through coinmama, of a horrible wallet confirmation prior with my kyc requirements only to still wait for a response.
I was considering coinbase if they changed how they approach customer service but apparently things are still the same with similar complaints.
