Cell c horror

I've been dealing with cell c from last year receiving multiple calls from different people all advising me differently. It started last year when I loaded data from my cell c app onto my cell c contract... I then received the SMS notification stating I have successfully been loaded with the data I continued to use my internet services and only when I received another SMS notification stating that I had reached my monthly limit did I then realize what had happen, I immediately logged a fault with cell c after months of back and forth they agreed the issue was on their end and will pay me back... now sitting in February I face a new back and forth issue for the payment. Cell c much like any other provider is fast to debit but takes ages to pay back when they are wrong the service is terrible I had to call them on numerous times for updates on the matter only to be advised that it was resolved and they would have to log the issue again. I have reached a point where I no longer call and just leave it be but I will be moving to another service provider it hasn't always been bad with cell c but this experience was horrible in every sense of the word... bad service, lack of co-ordination they really need to train their staff and get their stories right
