Subscribe to a VPN (virtual private network). SurfShark or NordVPN are good ones. You can choose to have your internet activities filtered through hundreds of different IP address all over the world.
I think the the use a VPN is a smart move in general and should be part of your general habits for computer safety and privacy, but that should give the OP an option to avoid the IP ban.
The VPN will get the OP up and running, while he/she waits for the admins to address the support ticket. If memory serves me, support tickets can take one or two weeks, so a VPN is the best option.
