What would you do if you suddenly had an extra $120,000 in your checking account?

What were they thinking? A Pennsylvania couple woke up one morning to discover that their bank had deposited an extra $120,000 into their account. Instead of calling the bank to correct the error, they went shopping. Of course, the bank corrected their error thereby removing the $120,000 to put it in the correct account. Now that same couple is $100,000 in the hole & the bank is charging them $107,000 in overdraft fees. The couple is now refusing to take any phone calls from the bank. How would you have handled this???
