Vodacom consultants empty promises

I posted in Week 21 about a matter with Vodacom that has dragged on for almost two months. After speaking with Fazwaylah Gertse-Grammer at Vodacom's Advanced Data Solutions on the 20th May, I thought the matter would be resolved. I received a once-off letter of goodwill from them, crediting me R1395.14, meaning that I'd have to pay the outstanding amount of less than R200. I was told by another consultant from Accounts who I had to explain my situation to, on the 21st May, that the outstanding amount of around R200 that Vodacom asked me to pay after receiving their letter, could not be debited at the end of the month as I had requested and that I had to pay immediately for the line to be unblocked. This is after explaining to her that I'd been credited R1395.14. So I paid the outstanding amount and added a bit extra on the 23rd May. But alas, after speaking to Luan (Vodacom Brooklyn Mall), Palesa, Thandeka and Vinoliah (who said on the 23rd that my line would be unlocked on the 23rd) my line has still NOT BEEN unlocked. Even these SMS'es I've been receiving from them about rating them (Vodacom) on their service, just seems like a big joke now. Unimpressed and fed up.
