No service delivery for 2 years

I am being contacted by Dino Arends from Vodacom, but I have no means of contacting him directly, so I will respond here. I have been a customer of Vodacom and have had the same nr for approx 15 year, the last 6 of which had been on contract. I moved to Randburg about 5 years ago and I did not experience any issue, but then moved to Bedfordview about 2 years ago. In my area, the signal was extremely poor, which I reported numerous times. The response was that Vodacom knew about the situation (note that my complex was already built for 5 years) and that they are working on a new tower in the area. I subsequently moved before they did anything about it to Waterfall City, Midrand, where the issues are even worse! No internet signal and constant call dropping. I have begged Vodacom numerous times to provide a solution, without any success. I even tried cancelling my contract late last year, but they wanted me to pay some ridiculous amount (about 75% - R7500 of the contract). I finally decided to cancel this month and was charged R2700. I find it appalling to have to pay as this is breach of contract since they could not provide me with signal. They have no idea what service delivery is
