IMPOSSIBLE to receive copy of contract

I requested a copy of my contract, including the proof of purchase for my Smart Phone which forms part of the contract. I went to the Vodacom store, which informed me that they cannot assist me. Reason given was that because I upgraded via the phone, I have to request the copy of contract via the phone. I phoned 111, and after being transferred around endlessly, I was asked to send a copy of my ID via email, and also email a request of copy of contract. I sent the copy of ID 3 days later. Nearly a week later, I phoned again, only to be told that the request has been cancelled because I did not respond within 24hours, and that a call will have to be logged. Another 3 days gone, without new notification of logged call. I phoned once again. This time, the operator told me that the 1st call is still open, but they require official letter requesting the copy of contract. Very frustrated, I sent through the official letter. Another week passed, I phoned again, only to again be transferred from one centre to the other. Final word - the request has been passed to the warehouse, but it will take very long. But how they cannot tell me. Now I have to wait open ended to receive my contract.
