299 E 17th St, Costa Mesa“The T-Mobile staff were extremely helpful when my phone stopped being able to read the sim card and connect to the mobile network. My new phone came in the next day, and they assisted in transferring all the data from the old phone to the new one. Thank you so much!”
“Amazing customer service, transparent about costs and very informative on ways to save and what's best to go with. Will definitely use Blackstone Networks again!”
“I had a fantastic experience at this store. Madison was incredibly attentive and well-informed. After I explained what I was looking for, she quickly retrieved the exact item I wanted from the back and thoroughly explained all the details of the product. Alice was equally impressive, offering additional insights right away. Both made me feel very welcome and well-informed about my purchase. If you're looking for top-notch customer service, this is the place to go!”
“Val the manager is an absolute rockstar! She kills it every time with customer service. I cannot recommend her enough. She truly understands what it means to take care of your customer and goes above and beyond! I met with her twice and both were an absolute pleasure. If you need to switch or have an issue make sure you see her!!!”
“Went in on Saturday and thought we might have to wait, very surprised to helped right away by Vianey B. He was the most knowledgeable and helpful person. He knew exactly what we needed and went out of his way to be sure we were satisfied. The store should reward a employee of his caliber and knowledge about there services.”
“Can't say enough about Ryan, who dealt with several out-of-the-ordinary issues that I presented to him -- as well as a couple glitches in his own technical "toolkit" -- with exemplary patience and professionalism. He listened as I explained my situation and issues at a level far below his own, and offered all the options and alternatives/workarounds he could envision to get me to most cost-effective solutions.”
