Billing / Accounts Issue

I had a solid Vodacom account for probably the last 14 years. <br> In 2012 I got retrenched, still keeping the same Vodacom account.<br> I made payments whenever I could as I obviously needed the service, sometimes a bit late but always paying.<br> About a year ago I was suddenly cut off, I paid the arrears, sent an email to Vodacom enquiring about the suspension of service, with no answer to date. No surprise as their online customer care in non-existent.<br> I subsequently went to a Vodacom shop in Somerset mall, where a service representative suggested I open a new account as the current one ***) was closed.<br> I now received a phone call from Barnard, Germond & Associates\ informing me that I am R12 000 + in debt to Vodacom.<br> <br> I would like answers please
