    Esteban guaranteed the transfer of my information to my new phone and after hours of waiting... nothing was transferred. Horrible experience, he promised to look into resolving it, but never called me back.

    I’ll never return to this store and recommend going elsewhere.

    I had a wonderful experience at the store in Cos Cob. Esteban is wonderful! His customer service skills are excellent and he has a great deal of patience. I will always return to this store and request Esteban! He went above and beyond!!

    This is an ATT authorized retailer, not a corporate store so they don’t have to follow rules. Guy working there alone today 10/14/2020 said he didn’t have to wear a mask when we asked him. Just be courteous people, you never know who is immunocompromised. This guy didn’t care. Went in for two new iPhones and left with nothing. Definitely do not go to this location!!!

    Brandon Mota was super super helpful, which was not a small task during the “stay at home” time period. He provided his mobile number and communicated via talk and text to ensure we had what we needed. He also followed-up to ensure all was working. Great customer service!!! Thank you!
