I just went through a month of customer service hell with the Fat Cow technical "support" team because my outgoing e-mails were not being delivered properly. (They showed up in "Sent" and weren't going to recipients' Spam or Junk mail -- just were disappearing.) They were never able to properly diagnose or fix the problem. I eventually had to buy and install a new version of Outlook in order to get it working again (despite the fact that the former version had been working fine for four months prior to failing, and the fact that everyone else in the company is using the former version with no problems). Techs repeatedly asked me to go through the same steps, check settings, said they would ?escalate the problem,? and then got back to me with the same advice as before. They were not able to remote in to see exactly what was going on. When I finally snapped and insisted that a manager call me? he never did.
A couple ratings sites have given them C or C- based on customer service, and I would tend to agree with that assessment. Although their control panel and tools are easy to work with and fine, god forbid you have any problems you can't solve yourself.
