I sent off a support ticket, hopefully they sort it out, I was already in the process of moving a domain out anyway and was considering moving the others as they are nearing expiry/renewal anyway in a couple months.

I usually use Google Domains, they've been pretty solid for the last few years, the only reason I used Namecheap to begin with was because they were so cheap but now its almost the same price as most places to renew and theres little incentive to stay.

I hope it works out, good luck.
