Oh no! I hope they catch whoever did that! Good luck.
We had to set up a new acct. a year ago when some employee of our mortgage co. stole thousands of bank accts numbers with all pertinent info, no doubt to sell them. Thankfully they didn't get into our acct., but Iwe closed that one and opened a new one, plus I keep a separate acct. now to use for online buying and I pay bills through our bank's BillPay so that our main acct.'s number is never available unless I write an actual paper check which is rare.
