Woollies is *****ing with my credit profile!!!!

I settled my personal loan in October 2016. Due to various mistakes on Woolworths side I over paid by R36. The beginning of the year the call centre phoned me demanding me to PAY the R36 or they will have to take legal action. They really have idiots working for them. I have explained this so many times it is not funny. But they listed me with ITC as a "bad payer". I tried calling, only to be transferred from pillar to post. Now I don't get a peep from Woollies. I want my R36 with interest back and my credit profile restored.

Woolworths you *****ed me @ ITC , now un***** me.
