Planet Y.

I chose this host because of their cheap pricing - this was a mistake. Their customer support is atrocious - it took me more than 3 days to get responses to my tickets (a few times even weeks). I decided to leave these guys, so I cancelled my service. However, they continued to charge me. I contacted them regarding this, and was told that I didn't cancel my order (which wasn't true). Upon hearing this, I told them that I no longer wanted to have anything to do with them or their services, and that I'd like to get a full refund. They didn't respond, and continued to charge me for subsequent months.

TL; DR - don't be drawn in by their cheap prices. They have horrible customer service, unreliable uptimes and no regard for customers.
