Vodacom bad service ?

The service at Vodacom mall@reds is so terrible. I had to miss my meeting because of their poor service. The guy named Lesego should be disciplined because it was not the first time we experience just a service with him. He never finishes anything. I went to vodacom to get a sim swop. He told me the SIM card is registered and will be active in 2hrs and after 3rhs when I noticed it was not active I called vodacom line and only to find that he didn’t active him. And I told him I need it active as I am going to be away from the office and they should be able to reach me. I went there the following day and just before 9:00 and I was told by his colleagues that I should wait until 9:00 yet I was supposed to be at the conference at 9:00. Now there incompetence is costing me!!! What a bad service. They didn’t even seem to care about my story ??
