Terrible service

<p>MDB was handling an account of mine and i was requested to make full payment which I did. It is now two weeks later and they still have not allocated my payment and settled my account. When i called them they said to me I had used the wrong reference number however I had used the reference number they requested when they sent me a demand letter. They made me do an affadavit as well send through proof of payment which I did and they still cant locate my payment. When i asked to speak to a supervisor they said none were available</p>
