Worst Customer Experience with Woolies and MBD

I am very frustrated with Woolworth and MBD, so I had a credit card with Woolworth that was handed over to mbd with a capital amount of R 26 000. I've paid MBD about R 33 000 yet they say I still have an outstanding balance of R 29 000. Since when does a credit increase 100% in less than a year? Woolworth do better, find reliable 3rd parties to work with. MBD staff are very *********** and emotional, they cnt solve a single query all they do is throw u from pillar to post. They cnt even provide me with a statement to confirm what they talking about.
