Hours are inaccurate according to Apple Maps it says Monday-Friday hours are 10am-7pm.Well when I…read morecame here today Wensday June 10 at 430 pm they were closed lights off.Anyways thanks for the wasted time and hopefully you guys actually put the right hours next time.

I don't usually go out of my way to write reviews, but this place has genuinely the worst costumer…read moreservice I have ever experienced in my life. The women working (I think her name was Darling or something like that) was incredibly dismissive and rude. Rather than helping or explaining anything to me she simply gave me the phone number to costumer service. Keep in mind I had already called customer service the day before and they weren't able to help me. If I wanted to talk to costumer service on the phone I wouldn't have gone out of my way to go to the store in person. At certain points she was straight up ignoring me and had an AirPod in while talking to me. Instead of trying to help me she said I should go to another store. I've worked in customer service for many years, and I've honestly never seen someone who seemed less equipped to work with people. I understand everyone has difficult days, but part of working in customer service is treating people with basic courtesy and making an effort to help even if you can't solve the problem yourself. At no point did I feel like she cared or even wanted to try. I left feeling frustrated and disappointed. I hope this location takes customer service more seriously because no one should be treated this way when they're simply asking for help.

My daughter and I came in to purchase a high school graduation gift--a new iPhone 17 Pro…read more The store was very busy, but I could see that the employees were working as quickly as possible while providing great service to each customer. When my name was finally called (after waiting for 15-20 minutes), the Spectrum Representative, Carlos, assisted me with my purchase. Carlos, whom I have dealt with on numerous visits here, was super friendly, very knowledgeable, and professional. Carlos always provides GREAT customer service, and I truly appreciate his dedication to assuring that other customers and I leave the store happy with whatever they were here to do. Be it with cable or internet service, the purchase, or issues with cell phones and/or equipment returns, Carlos and all the other employees will always do their absolute best. The store is always clean and well-organized, with displays of a few of their products. Thank you for another positive shopping experience.

Review for returning my equipment after terminating my Spectrum service. It was super fast and easy…read morewith their online appointment system. I arrived 15 min early and a minute later after checking in with their link, I got a text to go inside the store. Once inside, they took care of me immediately and the equipment return took less than 5 minutes. Fast and easy experience with no funny business! Unrelated to the particular store but I wanna rant about Spectrum: Was a Spectrum family previously at my old house and for 8 more years on my own account after I moved since that was the only good service available in my new home area at the time. Canceling my service took longer than I felt should on the phone... the agent on the phone kept talking to me and did all the typical sales guy talk to get me to stay. I hung up feeling extremely annoyed after successfully canceling.
