    Sales Rep. was alone when we arrived. Helped us thoroughly, even when another customer came in...didn't rush us through. Courteous and knowledgeable.

    I was at the store for an hour to get a SIM card and that didn’t even help did my phone. I had to go to the mission valley store, where they realized that my account was on a “data lock”. I didn’t even need a SIM card.

    The representative that helped us was friendly thorough and answered all of our questions. He made certain that we understood the product descriptions that we were considering and explained things that we were uncertain of.

    The store manager worked with us discussing different iPhones. He was very knowledgable. The phone I wanted had to be ordered, but it came when expected. Not a long wait. My previous carrier did not execute, on their end, the order correctly. Again, the manager worked very hard to get the problem fixed. I was impressed with his patience and his dedication to getting our transfer right. Thanks you
