I need DU help to solve a (possible fraud) mystery [View all]

[dixiegrrrrl]

We go to the grocery store once a week, same day of week. get a load of groceries, spend about 140.00.
Pay with debit card, get a few bucks back. Regular as clockwork.

Come home, and I enter the receipt amount into the $$$ program on the computer, same day so I won't forget/lose receipt, whatever.
Bank statement comes middle of month, I balance the account.

This time I happened to notice a grocery store debit, on the same day, for TWO withdrawals. One was in amount I had entered, the other, 150.00, no receipt for.
I know for a fact it wasn't our shopping.

called the store, mentioned possible fraud, they instantly checked their till records, and said that sale was not in their records. Hmmm..

called the bank, told them...store,dates, no record at store.

They said to come in, and immediately said they would re-issue new card, and put the amount back into our account. ( good local bank).
So problem correctly solved.

except...WHO took the 150.00? How did it end up being on our statement when it did not show on the store totals?
the bank seemed not all that surprised, they had instant response, and they are not talking. Which I can understand for obvious reasons, that they don't wanna share security info.

But...any dear DU Sherlocks....who got the money, and how?....
