Okay, WHY did nobody tell me this sooner?! 😂 Whether you're already with T-Mobile OR you're thinking about switching, apparently you need to check out T-Mobile inside Costco before making any decisions. And if you're anywhere near Puyallup, this is the location I'd check out. Daka is the person who personally helped ME. He was knowledgeable, attentive, patient, and made the whole process so much easier. While I was there, I also watched Alexis helping another customer, and I was impressed by the care and attention he gave them. So while I wasn't Alexis's customer, good customer service is something I notice—even when I'm watching it happen across the room. 😂 I can't speak for everybody who works there because I don't know everybody there, but Daka took great care of me, and Alexis definitely stood out from what I observed. And I'm not exactly new to T-Mobile. I've been a T-Mobile customer for almost 30 YEARS. My relationship with T-Mobile started when I was serving in the Army in Germany, back when I knew T-Mobile as a month-to-month/pay-as-you-go service. Since then, T-Mobile and I have been up, down, over, around, and probably THROUGH the mountain together. 😂 Come to think of it, T-Mobile may be the longest commitment I've ever made by CHOICE. I was going to say being a sister, but I didn't choose that. I was born into it. 😂 So yes, choice-wise, T-Mobile and I have been together longer than any other commitment I've willingly signed myself up for. We've been through some things. 😂📱 So when I say I wish I had known sooner about going through T-Mobile inside Costco, I mean it. And now I've discovered Costco is where I can take care of my three F's: ⛽ FUEL 🌾 FLOUR 📱 FONE Yes, I KNOW "phone" starts with PH. Please don't mess up my three F's. 😂😂😂 Fuel the car. Buy the flour. Handle the FONE. If you're already with T-Mobile, check here before your next upgrade or purchase. If you're considering switching to T-Mobile, I'd check here too and see what options are available through Costco. Daka, thank you for personally taking such good care of this almost-30-year T-Mobile veteran. And Alexis, although you weren't helping me, I noticed how well you took care of your customer too. After all these years, apparently T-Mobile can still teach me something new. 😂📱 View on Google
