When will VODACOM do what they say they will do?

I have had a problem for 5 months. Finally I was told by Siphiwe Makhubo that ***** had been confirmed on my account and that ACCOUNTS DEPARTMENT would contact me. NOTHING so I called them but because my account is not in arrears I am routed to Customer Care. On Thursday 18 February I finally got somebody in Customer Care (Victoria) to make contact with the Accounts Department. I was told that PINKY would call me on Friday 19 February to tell me what was happening with the ***** case and how much I was going to be credited. Again NOTHING from them so here we are again, account up to date, month end account to pay and no relief. FRUSTRATING and VODACOM are ******* as they know I am dur a refund but continue to use DELAYING TACTICS.
