That is the downside of generic ATMs such as Rediteller and GoCash. I withdrew $500 from a Rediteller ATM but only received $450. It took me about six weeks to be reimbursed the missing $50.
Compare that to the Commonwealth Bank. I left $300 in one of their ATMs and apparently after about 30 seconds, it goes back into the ATM if not retrieved. I rang the bank a few minutes later after realising my mistake, told them the ATM location and ID number, time and sequence number. My $300 was reimbursed in two business days. That is why I ALWAYS get a printed receipt with any ATM transaction. If no receipt can be printed, I go to another ATM.
Same as a friend who withdrew $500 from a generic ATM. Instead of dispensing ten $50 notes, she received $200. Whoever cashed up the ATM reversed the hoppers, hence the wrong amount. And it took her over two months to get her money back. Not good for a pensioner!
Little bit off track, Veggiepatch, but here's another story about the downside of an atm, that includes hoppers, for those that deserved some bad karma.
40+ years ago I worked for a financial institution. It was just before 9am, before opening time, and the cretin known as the postcard bandit along with 6 mates hit one of the glass front doors with such force bits of it hit the back wall. Armed with the unmistakable look of AK47's and various other shotguns etc, they burst in as the atm was just being loaded up. Staff pushed the doors over and moved away.
Warning, skip this next paragraph if descriptions of violence might affect you.
The worst thing they did amongst quite a few was to press a 357 to the temple of a female teller and scream obscenities at her, and I do mean scream loudly, in her face, because she was shaking so much she could not manage to unlock the UCU in her tellers box. I've never witnessed, in close proximity, such a gutless and yet frightening act in my life, before or after the event.
To get away from the possible triggering for some, I'll stay away from the other traumas and stick to the atm bit.
The funny thing was that for such a smart arse bandit he and the rest of the thugs overlooked the noticeably opened door at the back of the atm and missed an easy $150,000 loaded up in the hoppers. ATM was right by the door that they had smashed in and exited from as well. Really good to include that laugh out loud bit whenever the subject was brought up by others. A genuine self tension breaker whenever reliving the circumstances.
Got another example when 2 years earlier I was at a different branch that saw most staff burst simultaneously into huge but nervous laughter at the blokes efforts to exit the building. But It'll have to wait for another day.
