- LGLisa GalloAug 28, 20265.0Friendly staff, but they are under staffed at the front, they need a self service area. This would help the lines for prepaid packages & QR codes. Ahmed is very nice & needs more staff up front helping when there are two other cashier areas vacant.

- MDMonica DicksonAug 6, 20265.0I witnessed a saint at this location! I even called her St.Lucy because I watched her be so patient with a customer who was unprepared and was just confused. Lucy continued to keep her cool and was never annoyed by this customer. The line grew longer, it's closing time, she was alone at the counter. She had to keep repeating herself to the customer but never lost her cool. Customers were getting frustrated with that customer but Lucy kept doing her job. She had the patients of a saint. I will continue to come to this location just because of her work ethic with people.
