I’m ready to cancel this contract! MTN is a headache at the moment!

MTN is waisting my time. I took out a contact with MTN. The SIM card was received through DSV (where I had a bad experience) once the sim was received I couldn’t use it! I tried to call MTN on the weekend where no one answered. I called them today and they advised me the sim is not ricaed! I was told to go to an MTN branch! I called DSV they advised that they did sent the documents through on Friday. I called MTN back and they said they can’t check from their side if they have the documents I must wait for 2-3 days and see or I must go to the branch! I have had the sim now for 4 day and can’t use it now I must wait!! The sim is already activated and I have 10 days to cancel! By the time this is sorted out I can’t cancel if I’m not happy. At this point I am actually ready to cancel this contract! If I had know what a headache this would of been I would rather have gone to the branch and done everything at once! Will MTN be paying for all these calls I have had to make to sort out this mess and will they be paying my petrol to drive around? Why must I give all my documents through to DSV if MTN doesn’t do their job? If I don’t get a response by the end of the day from MTN I will be canceling this contract and go to one of MTNs competitors and rather pay someone else for good services!
