Cell C gives the worst service

Cell C has done it again, I wrote a review to complain about the bad service I had received from the cell C get more app, I then called in May month to have the service cancelled, I was advised they put through the cancelation request and that they would call me back, after 30 days have lapsed and they will then complete the cancelation process and, I was very upset as I didn't understand why I would need to pay another month for a service I couldn't use, and then they can only contact me to finalize a cancelation, I waited and no one called, I work and have a family, I don't have time to sit on calls to cell C all day every day, so when they said THEY would call me back, I was fine with that, when they attempted to resolve my previous issue, all I got was a statement saying apologies for the inconvenience and here's new log in details, no one called me no one explained what to do, and that was in May month already, meaning the 30 days have long time since come and gone, and now I get another bill with the Get More service included, meaning nothing has been cancelled, THIS IS ABSOLUTELY RIDICULOUS, I WANT A NEW BILL THAT DOES NOT REFLECT THE GET MORE SERVICE, AS IT SHOULD NOT BE REFLECTING FOR THIS MONTH AS WELL, IT'S SUPPOSED TO BE CANCELLED AS WAS COMMUNICATED TO ME, I DO NOT UNDERSTAND WHY IT SO HAD TO GET A SERVICE CANCELED THAT I HAVE NEVER EVEN BEEN ABLE TO USE AT ANY POINT, AFTER MY FIRST REVIEW NO ONE WAS BOTHERED TO EVEN CALL ME BACK, AND NOW I'M BEING BILLED AGAIN, AND I REFUSE TO WAIT ANOTHER 30 DAYS, WHEN IT SHOULD HAVE BEEN HANDLED, AND THEN PAY TWO MORE TIMES FOR A SERVICE I STILL HAVEN'T BEEN ABLE TO USE, BECAUSE THE NEW LOGINS DIDN'T WORK EITHER, THIS IS THE WORST CUSTOMER SERVICE I HAVE EVER RECEIVED, THE ONLY THING THAT HAS GONE SMOOTH IN THIS SERVICE WAS WHEN I SIGNED UP, AND WHEN I PAY, THIS IS RIDICULOUS AT THIS POINT I SHOULD HAVE GOTTEN A FULL REFUND, NOT BILLED EVERY MONTH FOR A SERVICE THAT DOESN'T WORK, CELL C, PLEASE REVISE MY BILL AND CANCEL THAT APP ON MY PROFILE AND PAY BACK MY MONEY
