Dollar Tree review: Given wrong product

We placed an order online and only option was pick up at the store. When we got back from picking up product we realized we were sent the wrong item. When we contacted HQ, we were told to take the product back to the store for a refund. When we got to store the store manager was VERY NASTY, would not hear us out whatsoever. The store manager stated she cannot do a refund only exchange and that we couldn't do exchange for a product she did not have. Told us to take items we were trying to return and leave her store. I tried speaking with her over the phone, she refused to speak to me. Told my co-worker that she wasn't going to speak to me any longer due to my nasty attitude. All I was doing was giving back the same energy I was getting from her. I heard her tell my co-worker to leave the store and was very loud about it instead of trying to correct the issue and make it right for the customer. We were treated like if were trash, kept stating to leave the store. When asked for her name as I wanted to report this to Corporate she refused to give us her name, just kept yelling at my co-worker to leave the store. This was so humiliating to be treated like this in front of other customers at the shop. When I told her that they gave us wrong product she immediately got defensive and started being unprofessional with myself over the phone. We are in the retail business & ALWAYS try to find a solution, hear out the customer specially if we as a company made a mistake instead we were treated like a nuisance and made us feel worthless. She then stated that she did not make this mistake that it was corporate, I told her that she as an employee & manager for Dollar Tree company so when I state "you guys gave us the wrong product" I was referring to Dollar Tree not her directly. After that she refused to speak to me, handed phone over to my co-worker & told him that she wasn't going to speak to me any longer due to my "Nasty attitude" & started kicking out my co-worker.
