Failed service

I have had network problems since October. In November a networking person came to my house to test the signal and said that in two weeks' time, someone would contact me because the signal was too weak. By January i still hadn't heard from anyone in the networking department and the service was intolerable so I tried to cancel the contract. Finally after several calls and much frustration they have cancelled the contract and collected the phone. However, I'm now told that I can't port my number for seven days. So no one will be able to contact me on my no for seven days unless I get a new number and send it to each and every one of my contacts. In this day and age, you'd think that once the contract was cancelled and as a customer we had lived up to our part of the deal by returning the phone, we could port the number. So all in all, even once the contract is cancelled Cell C continues to ***** us. Lovely!
