Utter disgust for Cell C

I have a WiFi contract with Cell C it was taken out in 2017. The contract is due to end in June 2019.. I went into Galleria Cell c on the 2nd May and requested a settlement which they advised would be R42. I then made the payment immediately and forwarded the proof of payment to ********** bare in mind the billing goes off on the forth of every month. And my payment was made prior to this date. The SLA I was given was 48 working hours however my mail was only rep**** to 28days later... I cannot understand why I need to be penalised for this because cell c is negligent! This payment should have been picked up the very next day on the bank statement. This customer service is completely pathetic.. We are now being told the last debit order will take place in July which is ridiculous. When I went into the store again with my proof of Payment the consultant called the relevant department and I spoke to Desiree from the billing section.. they then advised I would have to pay for the month of May. This would have been acceptable however now I'm hearing a different story. This has been unacceptable and disgusting service I refuse to pay for what I have requested to be canceled. This matter needs to be rectified. I need someone toto contact me urgently by tomorrow 24.05.2019 on ********** 686.
