I fail to understand why you are coming to a Home Repossession website to ask for information on ATM withdrawals when the obvious place to go is your bank!(posted 8169 days ago)Go and see your bank immediately. If money has been withdrawn from your account then it will be on their records. If there is a problem with the ATM of the bank you were using, then there should be a record of that too. It is also possible that the ATM you tried to use had been tampered with so you couldn't get your money.
But see your bank asap - you should have rung them as soon as this occured.
