CEll C Horrific Expereince

In October 2020, I placed notice to cancel my cell C lines ( 2 numbers ). I spoke to CHIFUNIRO PHULUSA who then provided me with the amounts required and further advised on the dates of termination. I paid R3388.08 and emailed this proof to Chifuniro from CEll C. In response he confirmed the payments and date of cancellation on both lines. We further confirmed that I will retain one of the numbers as prepaid. A month later i received a further statement requesting an amount of R234.02. I proceeded and paid this as well and emailed the proof of payment to cell C. To my anguish in December I received another statement requesting a further payment. This indicated that the line was still active. I emailed CHIFUNIRO PHULUSA but it turns out that he no longer works for CEll C. I then called to the call centre and spent 59minutes with the consultants...Nondumiso Ndimanda advised that the amount of R3388.08 was part taken for my bill and the balance was left in advance for the new month. How horrific is this, knowing I have everything in writing and to hear this garbage. I also suggested that they get their billing/technical division to look into the usage on the line and that they will find zero usage as I knew the contract was cancelled and I destroyed the sim card. I then asked to speak to someone senior, i was placed on hold for 12 minutes and then advised that Sibongimpilo Ncube will call me back in 48 working hours. In the interim my credit scoring is impacted as I am noted as a non payer by Cell C for this most recent month. This is a horrific experience of incompetence and poor customer service. Reminding why i wanted to move away from CEll C.
