Vodacom Cancelations

I have asked for an early cancelation in July. I paid the settlement amount and send through all the required documents. After 4 months my contract has not been cancelled and my settlement amount was used for credit. After many phone calls and emails. My contract has been canceled and I was promised a refund for the months debited. I have not recieved my refund yet, instead another account for R1100 Lesley Deane I have mailed you twice and you have yet not answered one. Very disappointed with this service provider
