Has anyone else had their SSBT or shop slips fraudulently paid out before you've collected them?

I recently went to collect a few winning SSBT(self service betting terminals) slips. When I
scanned them it said already paid out. On informing the shop manager I was told they were
cashed out 2 hours after they placed. I left the shop immediately after placement and no other
person had any access to these slips. I suspect an inside job but the bookmaker in question has
no interest in helping. I have contacted IBAS regarding the case and they are assisting me at present.

Has anyone else had a similar thing happen to them, either SSBT or over the counter bet slips?
I would be interested to hear you story
