Account Switching feauture is frustrating...

I was adding my 2 alt accounts; I added 1 alt account and then my 2nd alt account asked for phone verification to log in, I verified it with the phone number on my MAIN account, and Discord removed that phone number from my main account WITHOUT MY CONFIRMATION. (My main account has 2FA enabled) Then I get an email saying that the 2nd alt account was disabled due to spam and self-botting, even though I NEVER use that account nor have I ever attempted to modify any discord accounts for botting or spam purposes... :/ Anyhow, I then tab back into Discord, and it's asking for a phone verification on my MAIN account, BUT after I verify, I get an error saying "INVALID NUMBER". MY COMPLAINT AND REASON WHY I AM FRUSTRATED IS... That I contacted support, and all I gotten was some useless quick-responses that had NOTHING TO DO WITH MY PROBLEM. - I emailed them regarding my issue again, but I got NO RESPONSE/SUPPORT whatsoever. It's been almost TWO 2 WEEKS that I haven't gotten a response or any useful information regarding my error.
