Worst Service Provider Experience I've ever experienced.

With fibre being installed in our complex I was quite excited to sign up and start using it in our home. I ordered the installation 3 months ago (end of October 2017). It took 2 and a half months and multiple phone calls before an installation team came to install. The team that installed was very good and setup quickly and efficiently. However they informed me that the installation outside at the box hadn't been done correctly and another team with the correct equipment would need to come and re splice. They said they had requested this service and the other team would be there within 2 hours. This was the 18th January 2018 and it is now the 30 January 2018 and still nothing. I have phoned the Vumatel call centre 5 times, the first time on Friday the 19th multiple times during the day and not once getting through to anybody. I have phoned 4 times since then, speaking to different people, all of whom have told me a different story but telling me that they would check with some team and get back to me. I have confirmed my name and contact number with them each time and have still yet to receive one call back from any of them. If this wasn't so frustrating it would almost be amusing considering that it beggars belief!
