Sky has been criticised for its customer service by one of its satellite subscribers who wished to sign up for an online offering.

In a letter to the Independent, an unnamed customer has described how he/she changed his landline subscription form Virgin Media to BT in order to take advantage of the "free broadband" offered by the provider to its TV customers.

The customer was then told by Sky that his local exchange did not have enough capacity to facilitate the service he/she required.

The disgruntled subscriber said: "I believe that since my problem is Sky's fault, it should supply this service at £5 per month, but it refuses.

"I am also unhappy with the way Sky has dealt with my complaint, which I have spent weeks trying to resolve."

Rumours surfaced last week that Sky is planning to put up its broadband prices by £5 for those on a 'free broadband' deal, unless they sign up to a Sky Talk phone package.
