Warning T-mobile is sending the wrong Sim size

So I got my phone today and noticed that T-mobile sent me micro sim instead of a nano sim. I went to the T-mobile store near my to get a replacement sim card. I don't know why but something told me not to deal with the rep I was in line waiting for, it seemed like everyone he dealt with ended up pissed. I didn't listen *first mistake* and stayed in line I got up to the guy and I told him what was going on. He just grabs the phone out of my hand and says maybe you're just sticking it in wrong. So he tries to jam a micro sim into a tray made for a nano sim and manages to get it in. I said what the hell are you doing I just told you it was the wrong sim size, then he was like well I guess you're right. When he tries to get the sim card out he can't, so he takes it to the back to "work on it" 20 minutes later he comes out with my phone in his hand, I'm thinking alright got my new sim and everything is good to go. Boy was I wrong, the first thing out of his mouth was "well we had a little problem" and shows me the sim slot. Well the good news is he managed to get the sim tray out, the bad news is the sim card was stuck inside and it looks like they damaged the pins trying to get it out. I was like you're kidding me right and asked to speak to a manger because I couldn't deal with him anymore. The manager offered to replace it so he goes into his system and then tells me he can't place the order because the phone hasn't released yet. He told me I have to come back Friday get one if they have it in stock. Now I have a 800 dollar paper weight mocking me
