Acqufin claims that I owe them thousands; this is *****, but this company.

Acquifin unauthorized access Acqufin did the same with me. This company has reported on my credit profile that I owe them thousands and i have never taken a loan out with them. It dropped my credit score. I try calling them but the line goes dead to find out where they got my information from and what is going on. I sent them and email and a query to call me back but no luck or response..
