My father-in-law has recently had his phone line cut off due to not paying his bill which was set up as a direct debit. On looking into this problem we find that in fact he is paying two telephone companies for his phone rental. He is locked into two contracts one for 12 months and the other for 24 months. I have two questions. 1 how do we cancel one of the contracts and 2 how do we stop him signing up for services etc over the telephone.
