Here is my experience with Hostgator.
This company provided the worst service of any hosting company we have ever hosted with (and we have hosted with dozens about a ten-year period). Our server sent out listing confirmation emails and hostgator shut it down without any warning or attempt to contact us. This was a major site and caused extensive damage to our operations. They said we had exceeded there 200 emails an hour limit. This was not a continually ongoing process at that time and probably only exceeded their limit it by less than 100 emails within that one given hour. We then quickly made the decision to move our site to another host at that point, and after getting access again to our server, we moved our entire site to another host. Then we filed a cancellation form per their instructions back in January 2008, but they never cancelled our account (it's now May 200
. Then, we filed the form again several days ago when contacting them about the problem. They have consistently refused to close our account, causing us to waste an enormous amount of valuable time dealing with this issue. They finally sent us a notice it was closed, then two days later sent us another notice saying it wasn't. They have continued to utilize stalling and delay tactics to avoid giving any type of refund (their satisfaction guarantee is a farce) and keep the account open so they can charge our card again. All site owners are warned to never host with this company, not only do they have ridiculous limitations on almost everything hidden in their contract you agree to (when trying to act like they give you the best deal with unlimited everything), but wait until you try to cancel your account--a living nightmare. This has gotten so serious that we have filed complaints with the BBB, FBI, and FTC as it now stands. We highly recommend that you check their BBB complaints (there are a lot of them).
