United Insurance Company of America mailed my check to the wrong address Saint Louis, Missouri

I submitted my form to surrender cash for my policies the last week of August.  Finally, both checks were mailed on the 7th of September in standard mail!!  This is a great way of showing good customer care.  I can't trace the mail at all.  Since it was mailed to me in standard mail, I receive it on the 13th!!  At a great level of disappointment, one of the checks was present. Making a long story short, the second check never made it.  It was mailed to the wrong address.  I do understand that mistakes can happen but I called several times explaining my check situation.  My account numbers, name and address was verified each time.  It took exactly two weeks for someone to search their system and realized the address was incorrect!! 

I realized everyone makes mistakes.  It shouldn't be an inconvience to me at all.  Why am I the blame? United Insurance Company of America wants me to wait until the check is mailed back to them.  Remember? Standard mail-another 7 days before it reach their location.  If the check isn't mailed back, I have to wait  30 days before they issue another one!!  Its 24th of September- nothing!!  Not even a courtesy phone call.  Matter of fact, they explained to me their procedures of mailing another check.  I didn't change my address or misplaced the check.  They made a careless mistake!!  Whats the procedure when the company makes a mistake?  Whats the procedure of correcting the mistake and keeping a satisfied customer?
