    Juliana was friendly and helpful. She resolved my problem with my iPhone.
  • full starempty starempty starempty starempty star1
    BEWARE!!!! THIS IS NOT AN OFFICIAL AT&T STORE!!! Spoke to AT&T Corporate who informed me they are NOT an AT&T store and therefore do not have to follow their policies. The will sell you but will not fix issues. I've had an issue for months, they will not help me, they will not send me notes that prove my account is at $0 balance. Do NOT TRUST THEM!
  • full starempty starempty starempty starempty star1
    DON'T GO HERE! They are scammers. I returned a router on Oct. 3rd, 2020 and STILL getting bills from AT&T for service contract that should have been cancelled when router was returned. They most likely did not return the router (they have NO SHIPPING INFO PROVING A RETURN) and they are using the service under my name. RUN and tell everyone NOT TO GO HERE! I've seen lots of the same feedback and have sent it and my experience/receipts to the State Department for fraud.

    My husband and I visited the store yesterday afternoon and one of the employees was not wearing a mask, it was very disturbing - we waited a couple of minutes and still no mask and no one remarked on it. It was unacceptable and very disappointing. We left and went to the ATT store on Greenwich Ave where the team was more professional and the rules observed.
  • full starempty starempty starempty starempty star1
    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.
