POOR RESPONSE FROM MTN FOR URGENT PROBLEM

I was a ***** victim on the 6th August at a STD Bank ATM in Kempton Park. I tried to call STD Bank from my cell phone at the ATM but was unsuccessful with 13 attempts. STD Bank requires an itemized billing as proof of calls I tried to make in order to process a refund - on the 7th August I went to a local MTN store to obtain a form for itemized billing of which they then phoned HO in Jhb who would sent me the relevant forms but one week later nothing was sent. I drove to HO on the 19th August to get these forms. Went back to the local MTN office19 August had them to complete the form and faxed through to the ***** manager. Up to date no response has been received
