Default Will moto support advance exchange give me the exact phone color & print ?

I had my phone about a month now and i notice there is three bumps on the back small but hard and there is starting to become a gap where u can push and it makes noises and its getting annoying and kinda sucks since i only had it for a month.

Im wondering if motorala will give me the exact phone as i bought it after the 15 day return ? they were offering me advance exchange but im not sure if it will be the same with the lettering .
