Worst Cancellation process ever experienced.

Ticket # [CF097851] Worst Cancellation system ever. We have been trying to cancel our Fiber line for almost a month and a half now. We sent an email for cancellation to *** on the 31st of October 2019. We have followed your process as directed. We received communication on the 5th of Nov 2019 that Cell C Fiber was trying to get in touch with us. On the same day we responded when they can call us back only to phone the call center ourselves to find out what was going on and was advised that the ticket was closed. We have to follow up the whole time with the call center. Why do we have to do this? Your customer support is the worst that I have ever seen. We then received a invoice for Dec. Which we will not be paying because we already gave notice of cancellation in Oct. We want our Fiber line canceled with immediate effect that is all we need. But even this is a struggle.
