Unhappy Customer

I have account ( ********** ********** 79) with Woolworths and I did have payment arrangement with them previously but suddenly I received a calls from debt collectors regarding my account been handed over to them. According to my records I have never received any notice of intending to hand over my account to external collection agency. I have asked for proof of letter intending to handover my account several times but no one assisted me. My rights is being infringed as a consumer because I have never given opportunity to remedy my situation (paying my Account) Since National credit act is been introduced “to promote a fair, transparent and economic welfare of South Africans regarding ******* handed over of their account, I am shocked to see this happening again in South Africa.
