1XBet Cannot Send SMS Code for Withdrawal

I have been using 1Xbet for a while now without any challenges until recently. I am currently unable to withdraw from my account because they I cannot receive the SMS code in order to complete withdrawal request, no error reported, just count down to zero and when I request SMS code again, it repeats the same process. On further enquiry, I realized that I may need to do 2 factor authentication, even with that process, I still don't receive SMS code and no error reported, just countdown after count down. I have been in contact with 3 agents already since last week, they first told me that my messages may be full, I deleted all the messages on my cellphone, but still could not receive the SMS code, I changed devices, still I can't receive the SMS code from 1XBet. The last agent I spoke to said I'll receive the code within 48 hours and that was on Friday the 6th. When I write to them, they don't respond, I only talk to agents who do not know what to do.
