Real Canadian Superstore

Hi, my name is Karandeep Singh, I work for instacart in midland. I deliver groceries to the people in the area. On sunday at 8:30 pm I have got the order to buy groceries at real canadian store in midland. I have total 38 items in my order and I found 35 of them I was trying to find the rest 3 but I didn't know where it could be, so I asked the employee lady (corry) that do you know where I can find these things and she said which one, I told her that I already find all these but I dont know where these 3 could be, she replied we are not supposed to help you guys, I said i'm not getting it free, i'm paying for these as same as a customer. She replied very rude and then said asile6, 7, 10 probably but I dont know. I ask her what is you name she replied i'm Cory and im the manager. Then I went to checkout, I ask the checkout guy that who is manager here, there was a nice guy I told him everything he replied yes, she did wrong, she can't do that and them he called staff manager ryan d ambrose, this guy didn't listen I single sentence from me and he said yes she is not here to help you, he was very rude to me I told him many time that please listen to me. He didn't then I write is name on my phone and he said ok you want it this way, I will tell you what I can do, I will call instacart now. I have to deliver the order and then I left. Never wanted to go to any pc stores in my life. Worst customer experience I ever had.
