Terrible attitude! I was on the phone with the customer service on the day before I went to the store. They told me that I can pick up the new WiFi machine for my friend. I made an appointment online, and went to the store on time. I told the guy with a blonde hair that I’m here to pick up the WiFi machine. First they looked at me said “Are you sure?” I don’t know what does that mean. Do they not believe their customer? Or this is the way they greet the customer? After checking the account, they told me that I cannot pick it up for her, but she needs to pick it up by herself. I said “Oh! That’s weird! The customer service told me that I can pick it up for her.” They answered “NO! YOU ARE NOT LISTENING TO ME!” Their attitude freaked me out! I walk out of the store with my hand shaking.
I understand that the company has their own rules about handling the account, and I respect that. However, this company has to have the better training on their online customer service to give the correct information, and to train their in-store customer service attitude.
Why do you blame me not listening to you instead of blaming your customer service giving me the wrong information? If you are not paying for my gas for driving to the store and the time that I waste in the store, don’t blame me!

The store is poorly managed. No clear sign or information about the waitlist. You have to wait the same long line just for returning a modem and getting a receipt.

Outstanding Service from Steven and Allen at Stonestown Xfinity!
We visited the Stonestown Xfinity store on a Friday afternoon to ask about international phone service, and we were lucky to be greeted by Steven—an absolute gem! He was cheerful, knowledgeable, and incredibly helpful, answering all our questions with patience and clarity.
While reviewing our current plan, Steven discovered we were eligible for a credit that allowed us to add an Apple Watch and upgrade our plan—without increasing our monthly payment. What a pleasant surprise! We chose the model and color, and began pairing it with our existing iPhone 11. Since our phone wasn’t updated, the process took quite a while, but Steven remained calm, professional, and supportive throughout. He never made us feel awkward about our older device—instead, he guided us through every step, including troubleshooting, restarting, and syncing.
Allen, the store manager, also jumped in to assist with the pairing and upgrade process. Allen provided the new iPhone information to us with the detailed payment plan. Both Steven and Allen worked seamlessly together with other associates, staying past closing time to make sure every detail was handled. We were the last customers to leave the store. It was already dark outside, but we left feeling so uplifted—not just because we had new phones and watches, but because we received truly exceptional service.
During our visit, we saw other returning customers drop by just to say thank you to Steven - proof that this team builds real relationships under Allen’s leadership.
Steven and Allen genuinely listen, learn, and care about each customer’s needs. Their dedication, kindness, and professionalism made our day. Highly recommend this store for all your phone upgrades, questions, and tech needs. Thank you both for a wonderful experience!
