Paid up Letter

I would like to complain about Woolworths Store. Woolworths handed me over to MBD for not paying them which is fair enough. I started paying them which made me to be in a credit of R607.00 with Woolworths but available reflects as zero. I contacted Woolworths Store (recovery department) on *** on many occasion and they keep on referring me to MBD to get a paid up letter. I informed Woolworths Store that MBD said that they don't have my detail and I need to speak to Woolworths Store in order to clear my name and to know my account status. Today ***5 at 14:40 called Woolworths Store spoke to Ms Sumaiya who referred me back again to MBD I explained to her that I am tired of going back and forward and I am not getting any joy. I really need to know my status of Woolworths Store and get the paid up letter. Woolworths Store account number:***. It is over six months now.
