Absolutely unacceptable service

Settlement on my contract has been settled almost a month ago, still being invoiced. The representative at Mayville Vodacom Chatz was no help at all. The payment was done at Vodacom Chatz which Katlego received the payment and did not phone me back on my enquiry. It is almost two weeks now and no one has resolved this. I am still being billed for a contract settled in full. All required documents as well as POP was sent to early cancellations. Nothing has been done to resolve this. I will not recommend Vodacom to anyone.
