POOR SERVICE DELIVERY AND CONTRACT HANDLING - CELL C

I've been a Cell C client for many years now, but I have to say, that I am not impressed with their service in general, anymore. My latest contract started last year August, till now I only have problems. I feel like I am harassed by them now with a payment which, according to them, I am in arrears. Fact is, since the start of my new contract they kept trying to deduct my debit order from my previous bank account which was closed 4 years ago. When I contacted them it was clear they did not rectify my details as instructed when my previous contract was taken out (it was also confirmed with the latest contract). Since Nov 2023 I am paying my account as a cash client. The past few months, even worse now, every day this week, I have been called and asked when I will pay the outstanding amount. The more I refused to pay, giving the reason why, the more they phone me. For 3 months they penalize me R70 per month because they cannot get a debit order paid through my bank... but, in the meantime I am paying on the 25th as I see myself now as a cash client. Why would you try to deduct money from a bank account through a debit order when your clients bill is paid up to date?? Am I the only one struggling with them or are there others? I'm just wondering. Today I found out that if you make 3 consecutive payments, 5 days before your debitorder date, you are automatically deemed to be a cash client... problem is, I am paying for the last year, 5 days before the debit order date, but still they want to deduct from my bank account. I am so tired of fighting this problem. All they can say is ..."Sorry for the inconvenience", but what are being done to solve the problem? Nothing, just harassment. The sad story of it all is, I am a client of theirs for about 20 years.
