Handed over for collection falsely

I left SA 2 years ago but before leaving, I paid Vodacom the outstanding balance of my contract.<br> 2 Years later, my sister gets an SMS from a company called VVM informing her that I owe Vodacom money. I contacted the number provided and found out it was a collection agency acting on behalf of Vodacom. I immediately contacted Vodacom, who acknowledged that due to an admin error on their part, my payment was reflected as a forward payment and not a closing of the account.<br> <br> You would assume that they would apologise for:<br> 1) Causing me undue embarrassment by allowing their hound dogs to contact my family - obviously a breach of my data protection rights<br> 2) Wasting my time and money (as I had to ring them from the UK).<br> <br> The very friendly chap in their legal department informs me that he cannot help me as the account was handed over for collection and I would need to deal with this ruthless 3rd party - who I had no contract with. This company has bombarded me, since, with emails on a near daily basis including weekends. <br> I emailed Vodacom and asked them to resolve this. I have had no response to this mail dated 18th September. <br> <br> Total lack of respect for clients - Disgrace
