I don't see what constructive answer you can expect in these threads other than "I work at <company> and I DM'd the CEO for you"; I've seen FAANG companies and Stripe respond that way here on HN, but never Discord.
The best alternative I can think of is "that sucks, rotate phone numbers and try with a new account" which is just as completely useless for OP. If that were an option, they'd already done so.
