No vodacom account but bad credit rating for a vodacom account!

I recently app**** for vehicle finance and was informed by my bank that I have a bad payment record for my Vodacom account - this information is appearing on my credit record. The issue is that I have not had an active Vodacom account for around 10 years. I have tried calling Vodacom a few times and have been transferred from department to department but no one can resolve this for me to get the ITC records updated. I did manage to get confirmation that my previous closed account is archived.

Please can someone from Vodacom urgently assist in getting this matter resolved.
