Vodacom harassing customers that paid accounts in full

If I could add a -1000 rating I would. These people harass you after you have cancelled your contract with them for payment on some outstanding balance which does not exist because they CANNOT provide any proof of an outstanding balance! And then they threaten with legal action but STILL refuse to provide a statement showing where the "outstanding" amount is!

We have a statement which CLEARLY indicates that the account is paid in full after the contract was cancelled! They are going to lose a lot of customers because of this bullsh*t!
