I have been with T-Mobile for many years, since the days of ‘One to One’. Generally, I have been happy with the service however of late I have become a little disappointed with them for reasons I need not got into now. I have become more concerned with the recent news of the ‘sale of private customer data’.
I cannot prove this however I am certain my details were passed on as far back as 4 years ago. I was called on numerous occasions, unsolicited; from a 3rd party who knew my contract was up for renewal.

Question, Is it at all possible that in having my details sold (possibly) on to a 3rd party, that T-Mobile are in breach of contract with me?
I ask this as their website clearly states that they will only pass on data to Group Companies.
Appreciate any advice.
