No feed back from Mweb after placing an order.

I am extremely unhappy, I have been waiting for weeks now to get my fibre installed, Mweb has requested proof of residence, I am renting privately and my landlord has provided me with a letter as proof that I am renting from them. Vumatel has delivered excellent servicebthey have installed the line etc everything they needed to do on their end. Mweb has now taken long and the only call I've gotten from them was to request proof of residence only after I've contacted them. I emailed the letter as an attachedment, I then didn't hear anything from them so I decided to give them a call, after calling the person on the other side of the line said no no no this is an email you typed, It was not I attached the letter with all necessary details on, they then said they will escalate the situation. I have already paid for the service and I am not happy that I have not been provided with a service as yet. I cancelled my lte within good time to recieve my fibre and have now been with out internet for weeks and wasting unnecessary money on data. I want this issue resolved now. I am not a person to easily complain but thia has now cost me a lot of money.
