The Better Business Bureau of any City is a worthless orginization that only functions to keep customers of their membership in the BBB happy. They have no enforcement powers. Any negative reports usually go to non-members of the BBB. Any member of the BBB rarely, if ever, gets a negative report even if they richly deserve it! Forget dealing with any BBB.
You should leave a report with the
