Bank escrow? ok, escrow payment service are a third party agent holds on to the money and when both buyer and seller agrees, payment go through to the seller. We pretty sure banks offer Letter of Credit, and they are not call bank escrow.
If that person you dealing with give you that word, I think I will think twice before dealing with him. Unless he means L/C, but L/C costs much more than escrow.com........ It is like some one email me and ask do you have the price of PS4 ? LOL
Best suggestion is, don't believe what he said, but call the bank and check it yourself, really, all you have to do is ask. Also, try to get this bank's number from google or yellowpage etc, don't use the number he offer you, good luck !
