Cell C and their ****ty service

I need an explanation as to how it can take over a month to cancel a contract when I have provided or off of payment to 3 different individuals, sent it to 3 different mailboxes and each time I follow up on a call nobody seems to know what they are doing. Each time I call I am requested to call again in 48 hours as they are still trying to locate the payment. On the 27th my account was debited even though there is an ongoing dispute which meant I had to go reverse the payment. Reversing that payment he *****ed me over as my credit score has dropped by a couple of points due to this incompetence. This has caused me a lot of stress over This post month trying to resolve this and I am frankly surprised by this treatment for a company of your stature and I am formally laying a complaint regarding this.
