Sadly poor response from Mtn

After receiving two faulty new cell phones, I refused a third one of that particular make. An Upgrade Reversal is required and the papers were duly sent to Mtn on 20th October. Numerous phone calls were made to this office by the local Mtn Office only to be told, twice, to re-send the papers. This was done, but still no response was forthcoming. In desperation I then phoned 808 on Saturday 14th November and when I provided the reference number which is ***2, I was told that the office didn't have that reference number. I was then given another number to call, which was not a valid phone number. I then phoned again and another agent provided me with yet another number which I called repeatedly only to have it cancelled while awaiting response from an agent, every time.<br> Meanwhile I am paying for an upgrade which I don't have. All that is required is to be advised that this Reversal has been done, but we just cannot get any action.<br> Surely there is someone at MTn who can fascilitate this matter.??
