I had a contract that expired more than a year before this incident happened. The contract turned to a month to month and I changed banks, somewhere the debit order didn’t get loaded on the new account. As I didn’t use the SIM, I didn’t notice until I got a call from a debt collector that listed me on my credit reports. I paid Vodacom the R400 that they couldn’t keep the company afloat without, they promised to clear it with the ITC...need less to say, over 6 months later it still shows that I owe this amount and I get no feedback and my mails get ignored. Transunion will not accept the paid up letter from me and says Vodacom needs to log it with them...but they won’t even do that. I would seriously appreciate a little small action from Vodacom to sort this out and get my credit score back to what it was.
