Went to simply replace my SIM card at at 1PM on Sunday. The hours are from 11AM to 7PM. The door was locked. There were people inside. After knocking on the door, a sales person came to the door and said they were closed for an emergency and that there were customers inside. I asked if I could just get a replacement SIM card. I was told to wait a moment. Another employee came and taped a closed sign on the door and never said a word to me or the other couple that was now waiting to get in. Very poor business practice. I drove all the way up from New Jersey because they had Sunday hours. Time to switch to Verizon!
