I had my photography website hosted through them for awhile, but then switched. I gave them the appropriate notification and shouldn't have been charged. They proceeded to bill me for THREE years! Every time they sent me a bill I would tell them that they were no longer hosting my site and I didn't owe them anything. Luckily they didn't pursue the unpaid bills, and eventually they stopped sending them. LOL
If it's a lot of money, I would complain until they gave me a refund. If you can eat the cost, just switch. My website is now hosted on a private server or I'd give you a recommendation. Good luck!
