Cell C Taking their customers for a ride

Got a new contract from cell C. 100GB day and 100GB night fixed home internet. Have had complaints logged for bad quality internet, Extremely slow when working, connects and disconnects all the time so working from home was impossible.logged 7 faults and called more than 20 times. within the first 20 days of having the contract I was without internet for 8 days. Called them to have the contract cancelled and now I have to pay more than R2000 for the cancellation. Did some research and found that cell c sold me a product that is not supported in my regoin. We have no LTE in my region. not even close or even in the neighbouring towns. I have had no support, no feedback on my reported faults and nobody able to help. everybody at the call centres just tell me I have to pay to have it cancelled. I have 4 contracts with cell c and have been a loyal customer for more than 15 years. I am not willing to pay for the cancelation nor am I willing to pay for a service I did not receive. Very unhappy with them and feel like taking all my contract over to someone else. Very bad service, very bad reception and the support is just telling me that I have to pay. Watch me and see if you get another cent from me till this is all resolved.
