fatcow they advertise money back guarantee but that is not ture. also they charged me double the amount they advertised. burlington , Massachusetts

I think this is another case of "The Devil is in the details".  There is one line in their terms that pehaps the OP can answer for their case.

If your plan includes a free domain name and You cancel within the first 30 days, a fee for the domain (and any applicable taxes) will be deducted from your refund. If you do not wish to keep the domain name, FatCow will take possession of the domain and the fee will not be charged.

- So the question is was a "free domain" included when you signed up, and did you decide to keep or give back the domain name?  My guess is that since you went to another hosting company the answer is that they did in fact keep the domain.  If this is the case then hard to call it a RipOff because you are still keeping a domain name that you can transfer to another hosting site, and they did provide a service in registering it for you. 

I just wanted to point out that stating that there is a 30 day money back guarantee and then not honoring it is not legal.  The fact that they had terms stating otherwise buried in a lengthy legal document is irrelevant if the 30 day money back guarantee ads made no mention of those terms, and the terms and conditions document was not referenced in any way.  A court and/or the FTC will look at whether the advertisement was designed to mislead a reasonable consumer, and while a reasonably prudent consumer would read all terms and conditions indicated on an advertisement (i.e. fine print), they wouldn't be expected to scour a legit business's entire website looking for scams, just in case.

And, if a consumer suffered an actual injury as a result of this misleading advertising, then I would think that the consumer would be entitled to compensation or at least a court order for the lousy scammers to return any money taken.  

Honestly, if this company is as shady as it sounds, I'm kind of surprised no one's brought a class action suit against them or something.

The home page says "money back guarantee," and the "learn more" page (which is the next page you will most likely see) says they have "30 day money back guarantee". None of these two phrases have asterisks or anything next to them, and neither page even have any fine print referring to any kind of refund penalty.

Sorry, but the average consumer should not have to click on the tiny "Terms of Service" link at the bottom of the page, then click on the "user agreement" link, then find the applicable terms in the sea of legalese. 

It may all be legal, but this does seem to be a sleazy company if they are this deceitful about the guarantee that they put prominently on the pages consumers will see. Cool web site though. 

intention to return it if it doesn't fit you.

Here's a direct link to their terms of service...and NO, I didn't have to sign up to access and read it and neither did you.
