Chowking review: service

We came at this brach around 9:38am to claim my gcashtreats for take out so they give as a number we wait for our order but they make us wait almost 1hr so we decide to cancel. How do you call that a customer service and chowing is a fastfood but why we need to wait almost 1hr if they have too many staff in the cashier.. Its the worst fastfood they dont know to give customer service.
