Oh well, it looks like I will never be able to join any Discord servers. 
Discord Support has been utterly useless. There is a serious problem, as I found my phone number associated with a different account (and deleted it). But a month later their system still says my phone number is already in use, and it is not associated with my account, in the Settings. And if I try and do the āphone number logonā it says THAT account is disabled.
But I have to ātalkā with a different āsupport personā (robot?) every time I communicate/email and they just read level 1 scripts about how the verification codes can only be used once and so forth.
Canāt make any progress on the real problem.
Total support failure. Sorry Pagle Discord, I really wanted to join!
