Wait for ever for your order!!!

I called the call center to place an order at about 18.11pm on the 29.11.2017 the agent that took my order said to me that it will be ready for collection in about 10 to 15 mins i then asked her are you 100% sure because the last time i placed an order i waited for an hour for my food she assured that my order would be ready in 15mins, when i got to the steers 15mins later i had to wait almost an hour for my order, my question is,WHAT IS THE PURPOSE OF PHONING IN,PLACING AN ORDER AND STILL WAIT AN HOUR, so i basically wasted my airtime and my time to just to wait an hour for my food and i was mis lead by the call center, i called the call center while waiting for my food and the agent said to me that i need to speak to the manager at steers lenasia and he cannot help me. Had i been told in the first place that i am going to wait soooo long for food i would have bought some where else!!!! Pathethic!!!!
