You'll be interested to know then just exactly how high in the customer service satisfaction table these two companies have reached in a survey by a well known consumer magazine for a phone line and calls service?
One was bottom and the other next to bottom with scores of 21 and 29 per cent respectively - you've no doubt already guessed which is propping up the rest.
One magazine reader described trying to get it to act as his most painful experience. "It's answering service is a maze. You disappear into the system, sometimes never to reappear."
Another claimed that its customer service is abysmal.
Yet ironically, although I use One.Tel for phone calls, my experience of one of these companies (BT) has mostly been a good one.
Perhaps it's just the area that you happen to live it that's the key?
