We had a XXXX XXXX walk away from us in the middle of a project. He asked for XXXX checks from us. XXXX in which I called XXXX XXXX to have cancelled - however they never cancelled the check and the fraudulant XXXX walked away with twice the amount of money he should have taken us for. I provided a customer service rep with the check number and the amount which needed to be cancelled. To my surprise a check for {$45.00} was cancelled instead of the check for {$7500.00} ( check number XXXX ). Since the following check to the fraudualnt XXXX was also cashed, I am at a loss of {$15000.00} instead of {$7500.00} due to harris bank not properly canceling the first check. When I spoke with Multiple layers of management, they told me there was nothing they could do because they claim I gave them the wrong check number. 
They should have never allowed the {$7500.00} to leave my bank account and should be liable for such a loss.
