I escaped from Talktalk a few years ago. They always plagued me with sales calls, trying to get me to change my tariff, offering me two months free if I switched to a new deal. I always cut across their sales pitch and asked if this meant I would be taking out a new 12 month contract. Yes, of course it did. No thanks then and please make a note on my account that I will never, repeat NEVER take out a new contract with you. But the sales calls kept coming. I used to just hang up.
When I finally got away from them it felt as if a weight had lifted from my shoulders. But what has really angered me about them is that I can find absolutely no way of shutting down my email account with them. It has remained live ever since I switched to a different provider and there is no option to close it. Which means, of course, that I am still vulnerable to any cyber attacks on their company. They have to be the worst internet provider in the history of internet providers.
