Poor service

Dear Vodacom, I don't have all the time in the world to deal with your ***********/ undertrained staff. I have been in communication with your staff for more than 2 months now to get your unauthorized upgrade reversed and there is still no joy after hundreds of messages and phone calls to and from. I must say they are trying their best to help me but I don't think they know what they are supposed to be doing. A lot of reversals and credits were done on my account but the account is still not back to where it was before the unauthorized upgrade. Also, no debit order ran on the 1st of this month which means something was not done correctly. I was told 2 weeks ago that my account is in credit and today it is in arrears. Can I please get someone who knows what they are doing to get this sorted ASAP.
