Worst service

After placing an order i went to walk in the mall. After returning from 20min walk came back to see if my order was ready i was amazed to hear people are going on lunch and busy doing other things. After sitting in the store for another 10min I politly asked when will my order be ready? The lady only then went to prepare the chips for my order? I then told her to leave the order and give my money back. Waited another 10min for the manager who first descuses the matter at the back with his team. Ive never ever been treated with such a dont care attitude. I can simply say that i would never go there ever again even if its the last place on earth.
