4 days with No Service and Sim Swap done on someone elses number!

Good Morning I am very unhappy with the recent service I have received from Vodacom. My upgrade date was 23rd March this year and I decided to upgrade to a Samsung A3. We went into your Chatz store at Broadacres and they completed the paperwork and arranged a sim swap. This was on Tuesday 19th April, we were advised that the sim swap could take up to 4 hours, the next morning neither of my phones worked, we called Vodacom and they asked me to turn both phones off and then switch on the new one. I did this and when I switched it on it appeared to be working that was until I received text messages from a child to her mother asking her to call her, I thought this was strange so I called my husband’s cell only to discover that I had been given someone else’s number. We called Vodacom again and they advised that we would require another sim swap and that we would need to purchase a new sim. The next day (Thursday) my husband returned to your store again, to try and resolve the problem. They advised that we would need to do another sim swap but agreed that we did not need to purchase a new sim as we had already paid for one that didn’t work. Ian at the Chatz store advised that it could take up to 24 hours to work. I spent most of Friday on the phone to Ian who had been calling Vodacom Technical for answers all day, by 5pm it was still not working that was day 4 with no useable cell phone, finally I called Ian and advised that if this was not resolved by Saturday I would be returning the phone and transferring my contract to Cell C. within 30 minutes of my last call the phone started to work with the correct number. I called Ian the next day to advise that it was working but as I said to him I felt that I deserved to be compensated by Vodacom for not having a phone for 4 days, he advised that I must contact Head office directly and that they would make a decision, I am completely dissatisfied with the services I have received as I have still be paying for a service I could not use for 4 days. I feel That compensation is the least Vodacom can do for all my Inconvenience. I have emailed the complaints department but as I suspected they ignore customer complaints!
