    How do you give NO STARS? My installation appointment was not honored. I could not contact the store or the manager by phone to inquire. I was not given an explanation. This is apparently the level of service I can expect from AT&T and this store. I cancelled.

    We got awesome service from Patricia R. She went out of her way to help get our phones upgraded and running. She figured out solutions to our phone problems. We will be back when need AT&T products and we will look for Patricia to help. She is the best.

    went in to purchase a new Samsung Galaxy S10+ they had none in stock proceeded with purchase my mobile phone acct. was past due so I paid with credit card phone purchase would not go thru because credit was posted to someone else account this issue took over an hour and a half with no resolution and no new phone. Had to return to store later to resolve issue this was finally done and after another hour finally purchased my phone which was mailed to me. The whole lengthy process was necessary it was like going to the DMV

    I TOOK MY OLD MODEM TO THEM AND ASKED FOR A RECEIPT; THEY SAID THEY COULDN'T GIVE ME A RECEIPT, AND WHEN I ASKED TO SEE THE MANAGER SOME SNOTTY WOMEN, WHO WOULDN'T GIVE ME HER BUSINESS CARD NOR HER LAST NAME NOR HER ID NUMBER REFUSED TO GIVE ME THE NAME OF HER MANAGER. SO I LEFT THE MODEM WITHOUT GETTING A RECEIPT. THE STORE WAS EMPTY, IM NOT SURPRISED WHY CONSIDERING THE ATTITUDE AND LACK OF PROFESSIONALISM EXHIBITED. I HIGHLY RECOMMEND THAT ANYONE WANTING A SERVICE PROVIDER SERIOUSLY CONSIDER SOME OTHER THAN AT&T, OR AT LEAST GO TO ANOTHER AT&T PROVIDER.HARRY
