no win win scenario for any of Cell C's customers

It's been almost 2 years now with the same problem, loss of signal, bad signal, no signal and bad congestion, spoke to so many people at cell c i cant even remember their names, went through so many call center representatives about 3 managers later, finally i was given an answer, cell c can not give me a time as to when the bluff towers would be upgraded, i dont know why they didnt tell me that in the first place, it would have made my life so much easier than for them to mess me around and give me false promises or wasting their time with sending out technicians when they could have told me in the beginning that they are not going to do it. Well finally i was given the option to cancel my contract, well 2 options actually, so after paying my new contract for over a year,i either have to hand in my phone to cancel, bearing in mind that i now own half the phone, or if i choose to keep the phone i have to pay in the rest of the contract, this proves that cell c's business ethics are bad and that no customer of their's will ever win, thank you Cell C!!! Whatever happened to providing a service and if you cant keep up your end then you are in breach of the contract you provided?!!
