What could be the reasons for the failure of the ATM (did not give out money, but wrote off)?

Question

Iron

Hello!
Withdrawing money from the same ATM many times with the same card.
Today, this ATM, when trying to withdraw money, displayed an error on the screen ("Hardware Error"), returned the card, and when checking the balance, it turned out that the money was debited.
In your personal account, the money is now in the processing status, that is, they are not on the account, but they are not listed in the list of expenses, as is the case with a normal withdrawal.
Now I'm waiting for the money to be returned back to my account, otherwise if there is a final write-off, I'll have to deal with the bank.
While waiting, the question torments, what could be the causes of this situation?

Answer 1

The standard error of the operation, the reasons for the sea: The transaction glitched, the path was jammed, the Internet sagged, as well as the ubiquitous small software is to blame.
You shouldn’t worry much, but it’s better to immediately call the owner of the ATM (usually the support phone numbers are written in the instructions above the ATM)
The money on your card was simply blocked before confirmation arrived, if there is no confirmation, it will usually be unlocked after 30 days.
The counter is not only on your card, your bank, but also at the bank of the owner of the ATM, the ATM itself, the cassette with money and in several other places - if the readings do not match, the "debriefing" begins
If the bill is stuck in the tract or you didn’t pick it up, then, I guess, after 30 seconds it goes to the reject box and is inventoryed and also investigated during collection of the ATM.
So the equipment is mostly protected from such glitches, only it’s usually given a lot a lot of time, and if a person’s salary is broken, then you have to wait for the next one, because banks are extremely reluctant to manually cancel locks, especially if the jamb was not with their equipment.
