Cancelled account and kept my money

Like most people I signed up my client with thinkhost because I valued their socially-conscious low carbon footprint web hosting. If I had known the problems that would ensue, I never would have paid them any money. My story is really quite simple. Due to some technical issue, I never received a welcome email detailing how I could access the control panel, and Dns transfer fields, etc. I sent them a support ticket, which was my first clue that trouble was brewing. At that time I also noticed a small message saying "sorry for the technical problems while we migrate our servers." (yikes, if I'd only seen that before!) Also, a comment on support-ticket systems; when a company does not provide any email or phone contact information, it is usually because they want a barrier between them and their customers behind which to hide. I'm not kidding about this, I recommend you Never do business with a company that uses only support-ticket systems for technical support. Anyway, I explained that my client was on a tight deadline and we couldn't wait for them to sort out their problems, and wanted to cancel the account. This was completely in accordance with their advertised money-back guarantee. After filling out the necessary online forms, I received an email saying that my account had been cancelled, sorry to see me go, etc. I could feel that something was wrong, so I kept track of my credit card statement online, and what do you know? They had cancelled my account without refunding my credit card. Keep in mind, I had never used their service for even a second, had quickly followed up in asking for a refund, had been polite, etc, etc. All this is moot anyway because they advertise a money-back guarantee. So again I sent another support-ticket, asking, quite assertively, for my credit card to be refunded. The email I received was the most bullying legalese I have ever experienced. They claimed that by paying them I had agreed to their contract (true), and that they would not refund my money at all. However the contract I had agreed to also stated a money-back guarantee. If you've ever been ripped off by a company like this before, you know the feeling. It's tantamount to be robbed on the street. You feel powerless and angry. This is how I feel now. Why would you want to risk doing business with this company? Why will they treat you any differently? A company which creates conflicting policies offering money-back guarantees in one paragraph and reserving the right to reject claims in another, is not a company dedicated to customer service, or social change.
