These folks are not idiots but they have to behave the way they do to collect money. I just "behave" right back.
Most agencies give a PO Box and an 800 number which is the road to abuse.
Look up the corporate information on the website for the secretary of state for the state in which the agency is collected. That will give the names of the corporate officers. Either search "secretary of state (State) or "corporate registration (State).
Then look up the real phone number on whitepages.com or switchboard.com
To find the state where the company is located, do a nationwide search on dnb.com (Dun and Bradstreet)
In the case of KCA Financial you will strike gold because the president is listed with his home address and his telephone number is listed on Whitepages.com.
The gold is:
David E. Widrick
925 Oak Crest Lane
St. Charles, IL 60175
Tel: 1-630-377-3136
It is perfectly legitimate to contact him at this address because it is the address of record with the Secretary of State for Illiois.
Ask for Mr. Widrick when you speak to a representative. You will be told he is not in the office or some other dumb story. Just ask if you should contact him at the above address and telephone number. I promise, you will enjoy the reaction.
