BAD SERVICE CELL C

My husband past away 1 1/2 years ago my daughters contract is in his name I tried to do change of ownership but was unsuccessful they said I have a bad credit record yet I don't have any accounts when asked for details they said they can't give it to me. I left it, the contract expired in Oct when they phoned me I said I will try again I submitted all the relevant documents relating the estate late. I have been to Cell C in Ballito with no luck. I have phoned the call center on several occasions have hold on forever they don't answer and when I get through no one can assist me and get told to phone back I tell them they don't answer and it is everyday the same thing over and over. I know am behond frustrated and this is costing me money on phone calls and petrol driving up and down. I just need them to change the ownership if they don't want to do that they must cancel my contract. I have tried since the 01 Nov phoning several times I have phoned a total of 30 times holding on up to 25 min some times. This is very bad service and every time they tell me the same thing. This morning when I phoned they didn't even have a Manger on duty and when he phoned me back later said he will investigate and phone me back on Monday. My daughter is in Johannesburg and we need this sorted now. I have been more then patient and DOESN'T GET ANY ASSISTANCE AT ALL. I NEED THIS SORTED NOW!!!
