Cell c service stinks

Unable to rate them after being in a contact for 2 years and ready to upgrade my phone was cut I had to pay R3600 this month to be told I still own another R2000 before they can reconnect my service and then speaking to a call centre agent from cell c and she advised me that from June I was billed for other services I did not request which pushed my account into arrears she cannot help me I have to call back Tomorrow but how can I with my phone being cut off. The best is this services I am being charged for does not even appear on my account how sneaky , she even said without those services cell c owns me money. I just cannot anymore I pay my account and the billing does not get correct on the next month bill. I am over cell c
