.....good, you work in contract law. So there must be at least one case where a utility/telecoms company has successfully sued a person and won, for cancelling said contract when the person never agreed to a new contract. Please provide details.

Make sure you look in all the Halsburys, all the precedents, all the appeal cases etc. A lexis search might be a "bit" quicker. Then please provide the case and reference number for said case.
