Ok, Im with bank of America. I got these 2 email about Overdraft. My checkin was empty and then when i got the emails and i checked my stuff on bankofamerica.com, i saw 100 dollars in the cheking. and I used to have like 400 dollars and i got payed so i deposited it, and theres like freakin’ money missing.
