No response on statement

I have on numerous occasions sent emails requesting statements for my Direct Axis account. When I call, I never get through to a consultant, only the automated voice that tells me that I'll be put through to a consultant, after that it just rings for over a minute and unfortunately I don't have airtime to waste! When I e-mail for statements to the queries@mbdcs or [URL Removed] as I always include both emails, I never get a response. What must I do in this instance because I don't want to be overpaying the account only to find out that someone else will buy the debt again and tell me I'm owing double or I've only been paying the interest and not the actual debt. Can someone contact me or make something happen fast or can I speak to someone in higher authority to assist me as it seems both your mailboxes don't get attended to.
