I had been an unhappy AT&T customer for years. The nonexistent service within Kingwood was the final straw. While doing my normal Costco shopping I saw the convenient TMobile kiosk and stopped immediately to transfer my service. Morris gave me exceptional service and helped me swap it all out in no time at all. There was a shop card promo that was really an added bonus. Better coverage, lower monthly bill, two new IPhones and a third line for free. After my phones arrived at my house (both were exactly on time/early) Morris sent me a text to let me know his schedule and availability to help me activate the phones. Sidenote ~ ALL of the staff were competent, professional and pleasant. They could and would have all helped. Due to AT&T and their dismal service the activation took a while. After things were ready to roll Morris went way above and beyond and let me leave the phones and go shop. No kidding. He later found me near the dairy to let us know he was done. Who sees this type of customer service anymore?!?! Fast forward and I’ve got texts and emails to activate my gift cards and shop cards. Once again I pop by the kiosk to ask for help. John & Genesis took time to lookup the total value of the gift cards because……well I’m old and need help. 😂 John went the extra mile, added them to my Apple Wallet and ensured I was ready to go spend them. I cannot say enough about this location. Costco well done for this added member benefit. View on Google

I popped into Costco today and talked to Sayed at T-Mobile, when I tell you this guy went above and beyond for me, I’m not lying. My iPhone XR stopped charging and I needed a new iPhone, this man hooked me up, got me a great trade in value and a new iPhone 17 pro max. The same as him. 10/10 professional salesman. I would recommend this guy to anyone. He made everything easy and wrote out my payment options. Thanks Sayed for making the stress of getting a new phone disappear. Can’t wait to take pictures of my cats on my new phone!! 🎉🐈📲 View on Google
