A netizen posted an anonymous complaint online stating that she was unable to utilise a $10 voucher that was given by a Gain City staff. When she was about to make the purchase she was told that the voucher is only valid for use on certain floors of the building.
However, It was not stated in the terms and conditions of the voucher. The last sentence of the voucher also states “Gain City Best-Electric Pte Ltd. reserves the changes and amendments to these terms and conditions without prior notice”
The netizen wrote:

Went to Gain City Megastore @ Sungei Kadut Dr together with my husband. Were given a $10 off voucher each when we reached the entrance by one of the staff.
We headed to level 7 and wanted to buy some items from there. However when we were about to make payment, we were told by the Gain City Staff that the vouchers were invalid. They said they were not aware of the promotion and it did not apply to level 7. The vouchers only apply to level 1 to 3, not 4 to 7?
We read the terms and conditions again. But the vouchers didn’t stated it was applicable for level 1 to 3 only? When we tried to query their staff, Johnny their Sales Manager was very rude and unreasonable to us. Because of their poor service and attitude, we decided to cancel the items and not to buy from them anymore.
Please, if the voucher is not applicable to level 7, then please state clearly on the vouchers. The voucher is so misleading. Will NEVER want to shop there again.

Here are what netizens think:

Just found out from my friends (neighbours) that they also kena from them few days ago. Their so called voucher is invalid at level 7. So level 7 is not part of Gain City?
Omg…. i have 5 of that similar voucher worth $50. .now I know. Won’t buy anything from there since cant use it at L7. Thanks for sharing.
This the problems when a small company grows into a huge corporation, every staffs thinks they are above all, Stay away than , that’s why sometime I like to go those smaller appliance store to buy my items
