Marketing excellent but service doesn't deliver, especially if problems encountered - customer services diabolical. Typical call centre setup incorporating all the usual barriers - problems not understood, unintelligent prompts reading crib sheets, transfers from pillar to post resulting in continuous repeating of problem, time wasting, difficulty in getting referral to management, unwillingness to confirm anything in writing - calls unlikely to finish within an hour, then have to again repeat whole process! Introduction of new charges/increases by stealth & refuse to justify by specific reference to the exact terms & conditions referred to. TalkTalk definitely to be avoided.
