ARROGANCE OF CALL CENTRE AGENTS AND SUPERVISORS

I have been a customer for approximately 10 years and for the past few month my bill has been increasing because someone at MTN removed my 2GB - data from my contract and i have been being billed for out of bundle rates.<br> <br> I called the call centre and was refused help and the agent requested i go to the nearest store. i asked to speak to a supervisior ( Lerato Bokale ) who instead of assisting me continued to argue with me without willing to listen to what I am requesting. I requested he send me via email why i am being billed these rates. He promised to send me a reference number for the call and investigate and advised the turaround time is 24 - 72 hrs. Called 4th december as . I called again on the 10th as Nothing happened but spoke to a different consultant who also refused to provide me details for a supervisor as i must wait another 7working days for the billing team to investigate and she PUT THE PHONE DOWN on me ( KEOLEBOGILE MARUPING ). How is that the processes of MTN dont allow a customer to obtain details of supervisiors or a porper complaints process. I have been billed wronfully and will not pay for the error of MTN. My number is ***. HOW DO I GET HELP FROM U
