No data,airtime or sms's

I *** upgraded my contract during November 2014 at above mentioned outlet on cell no ***. Since the start there were problems regarding the receiving of data,airtime and sms's on this contract . I called the call centre several times, but they informed me that on their side I receive my data, airtime and sms's. I went on the 10th 0f July 2015 to the Mooirivier outlet to lay a complaint. It was captured on their system but till now I have not received any feedback what so ever. The assistent named Beverley captured it. I still pay R189-00 from end of Nov 2014 but have no priviledge of using the contract as there are no data, sms or airtime now for the last 8 months. Either they suspend the contract or refund me as soon as possible!!!!!! I am highly disappointed in their service delivery!!!!
