bad service

I was just at the store now for more then 30min i am standing waiting for someone to go at the back to get the things i have came to pick up and have paid for and if i ask the girl(who i assume she is a manager) who does not even have a smile or a helping face how many more hours am i to wait and she tells me with attitude that she does not know the wen she lives the counter to help someone else I ask her so you going to go help another person while i wait another hour her for you then she tells me ohh you have to wait,so i had to live the store with nothing although i have PAID for it and she clearly said i can go!!!
