Good afternoon George,
As I mentioned, my goal is to provide you with excellent service today. Please don't confuse excellent service with a satisfactory outcome based on your wants and desires. I can only explain the law to you---not guarantee that you will be happy with the outcome---any more than a cancer surgeon can guarantee a cure.
Because the $8,000 check was never paid for by you, the bank was not legally obligated to give you credit for it---despite that it was a bank error which resulted in you getting the worthless check in the first place. The reality is that it was never worth the $8,000 because you never paid for it. Aside from the surprise factor you have not lost anything, and arguably you should have realized when you balanced your account that you had 8K more than you should have after you purchased the checks.
While it would have been proper business etiquette for the bank to have called you immediately upon realizing that they had made an error, giving you a chance to pay the 8K not the account to cover the check, the law did not mandate such a courtesy call. I imagine that you have a proper basis for the bank not to charge you an overdraft fee or a NSF fee based on their error---but that would be the limit of their legal obligation to you in this mess. I am sorry for the trouble that the bank cause you.
