I handle the finances at my company. Our company name is unfortunately really common. Think Smith Inc.
A month or so ago I got a call from a business we've dealt with several times in the past, saying that they had written a check for Smith Corp and accidentally mailed it to us, Smith Inc.
I checked our records and we showed absolutely no signs of having ever received the check. I called back their accounts contact, Hanna, and told her that. She was distressed and seemed to think that we must have received it. I asked her to fax over the back of the check to me, and if it really was deposited to our account, it would be indicated on the check. I received the fax from Hanna and sure enough, it was not deposited to our account. I told Hanna this, and thought the matter was over.
Next I got a call from Hanna, wanting me to sign and notarize a form saying that we had neither received nor deposited the check. It was a mild inconvenience since I had to go find a notary, but not a big deal. I did it and sent it in. I didn't hear back and thought that the matter (or my involvement, anyway) was over.
Today I got another call from Hanna. She launched into a complicated story about what was going on with Smith Corp, apparently the funds had been taken from someone's bank account, and Hanna wanted to know if the funds had been deposited to my account. Uh, no, there's no way that some random check that I've never seen before was somehow deposited in my account after being yanked from someone else's account. I'm honestly not even sure what the full story is, since I couldn't follow Hanna's account of it and it doesn't concern me anyway.
So I politely told Hanna that I did not have the funds, and I hoped she got it straightened out. Hanna seemed a bit deflated that I didn't offer to do anything to help, but this is SO not a problem on my end.
Etiquette wise, do I have any further responsibility to help out?
