Went in to sell a phone, told them what I was asking for it, the guy behind the counter checked it out, he then went to the back room to ask his boss and then made a counter offer. Then another guy walks in who was a former employee and he then begins to check my phone. The first guy made the statement that he just checked all the same stuff. Then the boss comes out and lowers his offer even more after I'd been there for 45 mins. I took my phone and left. Very unprofessional staff. Avoid this place.
