VODACOM FIBRE POOR SERVICE!!!!!!!

good day, i have a major issue with regards to vodacom's fibre division. first of all i cancelled my contract with vodacom before the ONT installation as i heard nothing from them with regards to installation and with confirmation from vuma i signed up with another isp as there was no records from vodacom to vuma for a contract as vodacom as an isp. after confirming my new isp i agreed to an installation date, 3 days later to came to my house to install and everything was up and running. two hours later received an email from vodacom confirming my installation has been completed EVEN AFTER MY CANCELLATION! NOW IM STUCK WITH VODACOM ON A 12 MONTH CONTRACT! they threaten me with cancellation fees as they have already installed! i decided to keep the vodacom fibre contract as i cant pay for the cancellation that i originally requested before they installed. so now with the vodacom contract intact a week later i still dont have internet connection, i have phoned the customer call centre 14 times in the last week and no one there can fix this issue no one comes to me or any offer to assist in any way. this is the most worst service i have ever experienced from anyone. MY ADVICE TO ANYONE THINKING OF VODACOM AS IN ISP SHOULD RECONSIDER!
