We've had similar issues with their customer support... yes, they really are *absolutely* useless.
We had to get our domain released and had a nightmare of difficulty doing so.
After getting no progress via email-tennis, we decided to phone 'customer support'. We were kept on hold for ages before getting through to speak to someone - this is all after finding no information on their site (of an ISP no less!) relating to our requirements. Then after discussing what we needed to do, we were suckered with the infamous switch, and passed on to someone else. Surely that could have done earlier? We did state what we needed at the beginning of the call, so why he waited and listened to our questions and just fobbed us off with nonsensical information before admitting it was too technical for him and needed to transfer us is cause for wonder!
Several phonecalls (and switches) later we were given the info we needed. We had to supply an official letter stating our requirements.We supplied the requested information in the *exact* manner as requested by Pipex (after asking them to put what we needed to do in writing) and then they had the audacity to turn round and say they needed some other info!
Our management were not pleased to say the least!
After much more experience of dealing with the faceless & useless 'customer support' we finally wrangled free of them. (Though they did hang onto our domain for longer than they should of, and still needed some further prompting to get it free.)
Lesson learned, although the 'customer support' was absolutely useless we voted with our feet and
found a better vendor. The Web is a big market, and if Pipex have useless customer support maybe it is because they're hinting we should be another company's customer.
