Disgusting customer service is a reflection of the business that is MBD

I just got a call for payment and when I asked for a final statement or settled amount the operator refused to assist me. She kept cutting me off and eventually ended the call. Absolutely disgusting. I have to verify who I am but MBD is not prepared to provide me with written confirmation of what I owe and the payment details. What a bunch of clowns, I would be embarrassed to work for such an organization!!
