Chikaan sa Cebu, SM City Cebu - complaint chikaan ayala branch

i used to pay electronic gift certificate whenever i visit your store., t'was my first time though to dine in ayala branch. i was never informed that they only accept even amount like 100 denomination., before i ordered our meal i let them know that im using ELECTRONIC GIFT CARD., i also ask them to calculate first the bill before SERVING THE FOOD., we're done with our meal and went out., we were about to ride a cab when one of your staff is asking us to go back to their store., it was embarrasing on our part because your staff is in uniform and shouting that we need to go back., of course other people will look at us thinking that they just went out of your store witout paying., this is very embarassing and ill make sure that this complaint will be posted in facebook. i need
