Woolworths financial services its a ****

I am having sleepless night because of wfs. I am now. Struggling to buy a. Property because of it. I was in an. Unpaid maternity waiting for my uif to pay and called woolworths financial services to. Arrange my monthly installments. They told me it is fine and they handed my account to mbd collections. A week or days after handing me over I received my uif money and called mbd to pay the areas I was owing to the store. I told them I will pay it cash on store which I did a day after they said they will clear my name, bit. To date I am still listed as a bad payer even when my account is up-to-date. I called them for a paid up letter but they could not assist. Now my. Life is stuck because of this shop. No one bothers to help
