No service!!!!!!

I have paid up my Foshini account in May 2015. Then i got as sms to pay R12.22 , which i then went to Foshini in the Bluff, Durban and paid up the R12.22 i asked what the amount was for, as i have closed my account. I was then informed that my account was handed over to Easton Berry for collections. They gave me a contact number, *** to sort out the problem. I have now phoned several times but i have been holding on for more than an hour every time. Then the phone cuts out. I went to Foshini Galleria today, just to be told the same story. Now i have phoned again and hold on for 44 minutes, but no one is taking my call. My phone bill is hundreds of rands for a stupid mistake of R12.22 on Easton Berrys side!!!!! Thus is totally unacceptable and i cannot even open an account or go to the bank to apply for a loan for a stupid R12.22 that is staying on my name.
