Paying s service at Vodcom which I am not receiving

Most horrible experience at Vodacom. I took out a Fibre contract by vodacom last year August/September. I app**** for a uncapped Fibre and then you receive Lte 100gb free. Unfortunately they have not finished installing my Fibre to make it live, so for the last couple of months I have been paying for a service which I am not receiving. When I phone everyone's response is they will escalate it and give feedback but I have never received feedback from them! The the calls I log they keep closing. Then we phone and reopen a call. I will not suggest to take Fibre by Vodacom. The service is absolutely terrible!
