Home Internet Issues

Well Vodacom does it again..I had homeinternet that was sold to me in KZN. to start off with the device I was given is a 5G device which never worked properly. I then moved from KZN to Clarens in the FS and that is when the issues started. Only to discover after 3 months of constant re-syncranizations that there is no coverage in Clarens. Vodacom then advised me that because there is no coverage they will CANCEL my contract. That is where the fighting started and I have NOT been able to stop them billing me and the phone calls started which could take up to 45min at a time. I was finally told I needed to take the device back before the billing could be stopped and to please be patient. I took the device back and have NOW been told THE CONTRACT CANNOT JUST BE canceled because when I origninally took it out there WAS coverage so I now need to pay a penalty to cancel the contract. HOLD ON its not my fault there is no coverage. ITS NOT MY FAULT YOU promised to cancel this HOME INTERNET but now YOU are saying you wont do anything and if I dont pay the penalty I will need to carry on paying for something I cannot use. OH and just to add insult to injury I not only have to pay a penulty I also have to STILL pay for the monthly subscription the monthly subscription IS STILL NOT GOING TO BE HAULTED.
