He gets to clock points by spending at the mall ($1 spending gets 1 point) and gets to access promotion deals as a member.
These points then can be used to redeem free parking or vouchers to be used at the outlets in the mall. For example, he can redeem a $10 voucher for 10000 points. 10000 is equivalent to spending $10,000 as a basic member.
He won a restaurant's dining voucher from a radio contest and decided to dine at the mall as there is an outlet so he can clock some points at the same time.
One day after he dined at the restaurant and scanned the receipt in the mall's mobile app, he wrote in to check on the status as it was the first time he using it.
A few hours later, he got a notification that he has gotten 226 points for his spending (double of 113 points due to an ongoing promotion).
A few days later, he received a reply on his enquiry.
He was informed that the receipt is not accepted due to the dining voucher.
The points he has been credited were all reversed.
226 points is equivalent to about 20 cents if he ever gets to redeem anything.
He wondered if he had not written in, would the mall actually discover the mistake?
