Incorrect Billing

I had a myGig 3 contract with vodacom that had already lapsed but not renewed.<br> I continued paying for it, and in November 2014 this was then upgraded **********ly, I noticed this with my December debit. I ldoged a complainant with Vodacom and was advised to get an Affidavit with the SAPS which I did. I was then issued this case nr S3-8WD12-297PE. After the internal investigations their legal department cleared me of all wrong doing and I have documents in writing of this.<br> However, their Collections department is harrassing me with Letters of Demand and listing me with the Credit Bureau which I think they have done by now. they are still debiting me on alternate months.<br> <br> I have wrritten to Icasa and Consumer complaint department about this and no resolution has come out of all this exercise. Is there an organisation or legal department I can take this up with? I am just fed up now with this.
