Regarding the customer service number been a charged number please be aware "Most of our competitors in the marketplace use 0845 numbers as customer service numbers - by doing so, they stay competitive by charging a small fee. We want to continue providing our customers with quality phone and Internet packages at great low cost. In order to do so, we have had to look at ways of cutting our costs so that we can pass on savings and provide a real alternative to BT with excellent call plans at low prices."
Yes, it is commonplace, but it doesn't make it right.
0845 produces hardely any income campared to 0870. Perhaps a 2nd e-mail might be in order to ask why these numbers are not included in their free time. They will reply back saying that it costs more to administer these calls on the grounds that the owners of the numbers receive revenue.
Other telecom companies can use freephone or geographic numbers as customer service contacts, and still remain competitive!!
