Vodacom billing me for months for a terimnated contract.

I am so ****ed of by these ****** called Vodacom. I complained last month about a contract I terminated but was being billed for months back and I am still debited. called them last month and last week but these blood suckers say they will call me to cancel but they don't. I am seriously getting to a point where I will act now. I once had issues with MTN and posted it on hello peter and they called me quickly and sorted it out. Vodacom call me on this number urgently *** / ***.
