NO WI=FI FOR A WEEK NOW

We have Vumatel uncapped fibre at home. When I got home on Friday afternoon I was told that the wi-fi is off. On Saturday morning I called Vodacom Fibre department and reported it. The person on the other side was very friendly and asked my for a MEC number at the back of the router. I gave it to her. Sunday went past and nothing happened. On Monday I called again and was told that the matter had been handed to the back office and that someone will attend to it shortly. They will also contact me to arrange a time for them to come past. I then called again later Monday afternoon and was told that they need the MEC number again as the technician who was attending to the problem didn't have the MEC number and could therefore not come to my house or contact me. I got very frustrated and told them I don't understand as I have already given the MEC number. On Tuesday I phone 3 times. I was told that the problem is with a person by the name of Renzo at the back office. When asking if I could speak to him I was told that they don't take calls but that they would attend to the matter. I was also told that Renzo should be in contact with me. I phoned in the evening again and was on the phone for 22 minutes and was told by a very friendly lady that she has been in contact with Vodacom regarding my problem. She said she would call me just after one on Wednesday as she is only going on duty at 1pm. I thanked her and was hopeful. Then at 2pm today I realized she still hasn't called me and called Vodacom Fibre again. This time the lady on the other side told me that my case had now been assigned to Mafelaelo at the back office. I then asked her if I could speak to his supervisor. I was once again told that they don't take calls but that I could talk to her supervisor. I waited and waited on the line and eventually had to drop the call as I had a customer on the line for me. I phoned again. While on this call she called me back and told me the supervisor eventually came to the phone but that I had already dropped the call. I was informed that he would phone me back within the hour. I am not holding my breath and will call back as soon as the hour is past. I am really frustrated as nothing is happening. My internet at home has been off for nearly a week now and no service from Vumatel or Vodacom.
