Mbd is a ****

I had an account with woolworths now mbd is collecting on behalf of Woolworths. Mbd is ******** people I made an arrangement with them since I'm not working so I was paying R150 from my child grant. In May I found out that my debt is still the Same they haven't been paying so I decided to pay direct at woolworths. Now they are harassing me they are calling everyday asking when am I paying this month, I told them I will pay direct to woolworths. I asked the other lady was calling me why is my debt still the same she said she doesn't know and I told her my story and said you won't get my money again. Today someone called me I told her I won't pay to you I will go to woolworths direct she told me they will call everyday I dropped my phone. This is a harassment I'm tired of these people. If they were paying my bebt wmto woolworths I'm supposed to be half way of finishing my account.
