worst lender I have ever used in my life! read the BBB reviews... not good

I received a post card from these people showing my current mortgage information, this was an advertisement from them, it was not in an envelope, just a post-card for all to read. Do they think that everything should be made available for anyone to read? Their answer to my concern was the information is available to anyone who might request it, my guess is that now my neighbors, the mailman and anyone else that may have handled that postcard no longer needs to request this information.
