Reported ***** on Vodacom account leads to harassment by debt collectors

I had a contract with Vodacom for 2 gigs data at R199 a month. I learnt that my identity had been ****** and that this contract **********ly extended. I immediately reported this to Vodacom's ***** department who promised to investigate and provide feedback in 14 days. I followed up a number of times but never responded to them. I have since been contacted by no less than 3 different debt collectors claiming that I owe Vodacom R700. Each time I have to dispute the claim and produce the emails sent to Vodacom's useless ***** department. It is such a harassment to have to repeat the story so many times and to keep submitting the same documents to different parties, not to mention the threats of reporting the matter to the credit bureau. I will not be taking on any more contracts with Vodacom and advise everyone to stick to pre-paid, or better yet, to use one of the other networks. The identity ***** also opened accounts with MTN and Telkom. They managed to resolve that matter once they received all the relevant documents from me. Vodacom on the other hand has been unable to resolve this in over a year! I am honestly very disappointed.
