My absolute worst web hosting experience was with Siteturn.com or Siteturn Networks. Not bad service, but just horrible billing practices. They overbilled me not once, and I had to go through a 6 month battle with them for charges that were kept appearing for no reason. They even kept billing me even when I left the company for another 6 months, until my bank decided to just issue a new credit card for me because the charges kept coming. And instead of actually realizing their mistake, they were very rude on the phone when I called to report yet another charge.

I suggest staying away as far as possible.
