frustrated

Last month I took a new contract with Cell C.I was given a ****le when I tested the ****le it did not work.I went back to the store I did a sim swap and the ****le did not work either.My husband went to Tygervalley Cell C shop and he spoke to the technician. The technician tried three simcards but the ****le did not work.He went again to Zewenvacht another simcard was given to him even that one could not work.The manager could not give me a new ****le and I was told the ****le has to be booked in and sent to the technicians.I brought in the ****le to the store.Since nobody contacted me I decided to e-mail the store and a lady phoned me back she said the ****le is back from the technicians and it was really faulty so the manager is off sick to proceed with the cancellation because when I brought in the ****le I told them I want to cancel the contract.I contacted the customer service I was told the store has to send the paperwork so that it can be cancelled.Up until today no-one contacted me and tell exactly what is going on and what to do.The store does not bother to contact me.I don't know what to do even the customer service does not help.I am frustrated because I'm loosing.
