Best cell phone accessory store in Upper Marlboro, Maryland (MD) 2024

I visited this store on 7/9/22. The published times list 9am. Although the lights were off and the door was locked until 9:13. I spoke with the sales associate and mentioned that I almost left since the store was still closed after the published opening time. He went on to tell me that his brother-in-law who is this general manager doesn't care about one customer because when one customer leaves five more customers come thru the door. I told him that I was sharing my customer experience and it was not meant to be argumentative. The associate was very combative and argumentative and sad all money is not good money. He asked me had I ever been late ever one day in my life.... WOW, just wow! Everybody has bad days but I think I will choose another location from here on out. This was my second time visiting this location. The customer experience is poor. ~Felicia
