Foodies and Credit Cards

I am asking for your opinion: Lunch at a less than memorable establishment with great friends that we have not seen for months. Friendship made the meal tolerable. I paid the check and add a generous tip. About 2-3 hours later, I happened to check my bank account. The bill which was $96.53 was withdrawn and a second withdrawal for $965.33. Certainly, I believed this to be a mistake that could be corrected by a simple review of the receipts from the last few hours and a quick chargeback. NOPE. After speaking to two managers at the restaurant, I learned that the waitress knew she made the error but decided not to tell me or bring me a copy of the voided charge. I have spent the last 24 hours attempting to have my monies redeposit into my account. I have spoken to 4-5 bank associates and the last person realized that this is crazy and put the money back on my account. I lost several hours on the phone, missed dinner plans, late to a play (that I thankfully paid for prior to this), late to morning meetings because I'm on hold with the bank, and stressed!! The whole incident left a bad taste in my mouth (and the food was not good enough for a return visit anyway) and enough anxiety to decrease my life expectancy by 1 month. What would you do at this point?
