Useless Cell C

So I have now logged six queries with Cell C in the last 4 Months with regards to my Cell Phone Account which is in arears according to them. But I have sent them all proof of payments needed to prove them wrong. They still can't sort it out, I wrote a review on this Platform where they responded a few minutes later to apologize for the inconvenience caused and I will receive a call shortly. I am still waiting for that call. this review was logged on the 08/09/2021. They in the mean time suspended my account twice. When Speaking to the consultant to sort it out I am told that my account is in arrears, when I asked them when my query will be resolved I am then told but there is no Cases open on my account, but when asking for a superior, the case is suddenly there and it is still in progress, Till now Cell C can't prove where my account is in arears nor can they resolve the issue, they just do not contact me. They now even tried to deduct the amount from my account on the 20th but my debit order is on the 25th of each month. So if I can provide you with some sound advice. Do not support Cell Ce as they are the most useless ISP i have ever come across, not even MTN or Vodacom is so bad, I am even willing to support Telkom. Yes they are slow but at least they get back to you and resolve your queries.
