I'm another satisfied Pipex Broadband customer. I did have to contact their Tech support only a few weeks ago, when the ADSL connection failed, due to a BT exchange fault. It involved two phone calls to Pipex on an 0845 number, each lasted about 15 minutes and cost 40p. The first call was to report the fault, the second to confirm I had carried out some simple checks, before Pipex contacted BT. On each occasion I did have to wait a short time in a queue, but both calls were dealt with promptly and efficiently by native English speakers! About three hours after the second call, the b/b connection was restored, and in the intervening period I was able to use a dial-up connection FOC.
At £23.44/month, I agree with Keef and PPRuNe Pop that Pipex now look a tad expensive, but my good experience with their Tech people means I'll probably stay put.
