Weeks later, police officers arrived on the Singh's door to accuse the Aussie couple of shoplifting.
The Facebook post reads:
“Surprise and shocked. We quickly apologised and said we didn’t know how that could be possible.
“The officers narrating the report made by Kmart said that he made the purchase, scanned the FlyBuys and just walked away to the car.
“Kmart staff, noticing that, followed him to the car and took a snap photo of the car registration.”
It is at this point where a flustered Ms Singh is asked by law enforcement to show the receipts of her week's old purchases.
"We usually don’t print receipts.
“I calmed down and took a couple of minutes to review our transactions on the card.
“The cops were professional and said that is good enough and we are not in trouble.
“I am so mad at Kmart Mt Ommaney management team for messing up my weekend and causing me unnecessary mental stress.
“(It) was quite embarrassing having the cops present in front of the house interrogating and was drawing a lot of attention.”
Singh then writes that the store and its employees caused her 'unnecessary metal stress'.
Kmart has since apologised to Ms Singh by releasing the following statement:
“We’re sorry to hear about your experience with our Mt Ommaney store,” Kmart wrote on the post.
“We can understand how disappointing this situation would have been for yourself and your husband, and we apologise for the inconvenience caused.
“We'd really like the opportunity to follow this up with you.”
