********** Account - Vodacom Does Nothing

I got a call from the contracts department informing me that i have to pay the cellphone account i have with Vodacom. I told them i do not have any account with them as the last account i had with them I cancelled it on early 2014. They requested that i fax my details so they can investigate and even now I haven't heard anything from them. Now i am struggling at work because when background checks were conducted it appeard as if I'm a ***** and i am certainly not! This is affecting my career life and Vodacom is not doing anything to fix it! I called their consultants twice, that was 3 weeks after i faxed the documents for the investigations and i was told nothing was received. I then sent an email with the requested documents attached with this reference number: S3-9OH2C-CIWLR and still no word from Vodacom. This is messing my personal and career life and all i get to be told is that there's none much they can do... My first an last contract with Vodacom has been a disaster hence I cancelled it after paying it off and never wanted to renew it. Now the same Vodacom comes and messes up my life.
