WORST service provider experience ever

WHAT MIRACLE MUST WE PERFORM TO GET ASSISTANCE FROM YOU PEOPLE? We have been without fibre since mid-February. We gave up a month and a half ago and cancelled our contract. We are STILL WAITING FOR OUR LINE TO BE RELEASED EVEN THOUGH CANCELLATION TAKES 30 DAYS WHICH IS LONG PASSED. We run a medical practice and need a fibre connection. Is Supersonic going to pay our Telkom bill for the data bundles we've had to purchase the past 3 months?! We are on the phone with you people just about every damn day but NOTHING IS HAPPENING. The standard response of "Your complaint has been logged" or "Someone will contact you" is not good enough because NOTHING HAS HAPPENED AND NOTHING WILL EVER HAPPEN IT SEEMS. Please just release our line so that we can open a contract with a different service provider. PLEASE!
