Very bad service

I phoned to enquire about my data contract. I gave the consultant the number in question. After holding the line for at least 10 minutes she told me I forfeited my data. I was very upset and asked to speak to a manager. I was asked to hold the line 2 more times. Eventually I was transferred but NOT to a manager. The second consultant told me the same thing. Then it transpired that they were referring to the wrong number. I asked again to speak to a manager. I was asked to hold the line 2 more times. Eventually I was told that the supervisor was busy and he would phone me back. When he eventually phoned back he couldn't give me an answer either. He said that he had no proof that I was given information, which, according to him is wrong. Why are we then told that conversations are recorded? Or does he not know how to retrieve a recording? Eventually, after holding the line again he said that he would log a query and it would take 5 days. Really, how long does it take to retrieve information from a computer? Al I have done the last few months is fight with Vodacom and I am now seriously sick of this bad service.
