Vodacom - customer service is a disgrace

Dear Vodacom I've been trying to do 2 things: 1. Change my contract (due to wrong info given by a salesperson). 2. Activate international roaming.

So far, I have made 4 phone class and had to 'hold on' for very long periods of time. First time, the call dropped, and the consultant did not phone me back. I phoned back the following day and was assured that Amanda would call me back. This of course did not happen. Then I spoke to Bongi - same story, system is slow, keep on putting me on hold and I had end the call as I had a meeting. I was assured by Bongi she would call me back. Yesterday, I tried again. The call took 59 min and 8 sec of my time. Again, same story - slow system, keep putting me on hold. I told the consultant that at the beginning that I am a very irate customer, that I cannot believe anything Vodacom consultants say and that there is absolutely no trust anymore. I asked to speak to a supervisor, but the consultant said that she would solve my issues. However, again I was promised that I would be called back - we even arranged for a time, 09:00 this morning. It is now 11:17 and no call. I tried to get a number so that I can call the consultant, but she indicated she cannot give me one.

Your customer service is a disgrace.
