2 Big issues
Security: My CPANEL got hacked multiple times, My websites got hacked multiple times.
When I tried to login to my cpanel the recovery email was not mine, it happened 3 times.
Customer service: Worst customer service. The online chat representative always closes the chat ON purpose. I am also sure they temporary block the chat based on IP or whatever means they use.
Very useless customer service.
You get what you pay for.
