Unverified Account? What?

I've been trying for 2 days in vain to phone their customer service department to no avail. I've emailed but no response. I tried the WhatsApp number, that too is dead.

I have 2 problems: 1. I tried to make a purchase on my account but it was declined due to "my account verification being incomplete". I successfully made a purchase a few weeks ago? I managed to get the account reinstated yesterday but that didn't help. 2. After I signed in and entered the OTP to complete the transaction, it was again declined for some unknown reason. I have more than triple the amount available on my account. I tried to purchase again, AGAIN the account verification was incomplete.
