Imperfection

I purchased a new iPhone Through Apple.com. I usually purchased my Apple devised at an Apple store physically so I can have help properly setting up my phone. I went to tmobile (my carrier) to have them help me set it up and put my protector and case on my phone and the representative said I have an imperfection on my screen that is making my screen protector bubble a little where it is. He advised me to contact Apple and request a new phone since my screen isn’t even but I have no other phone to use and since the stores don’t open until next week, I need advise on what I can do to return my phone for a new phone?
