Such crappy customer service

My husband went to work at 4am this morning and tried to use his card to buy coffee and it declined... Weird, he just got paid on Friday. So he checked his account and it was negative $700 with a $2000 check pending! He calls Chase to report fraudulent activity and they inform him that it was their mistake and they can't return the money or do anything about it until the check clears, which he then has to call them back and have them reverse it. This is going take days and he's just shit out of luck?! We are beyond displeased with this bank.

Edit: we did not write a check for $2000 and the bank told us that another Chase customer did and it was posted to my husband's account by mistake.
