What our customers are saying

  • full starempty starempty starempty starempty star1
    Edgar was great when I called and asked for information. I later called back to ask a question and Justin answered the phone. He lacked costumer service and he was extremely rude and condescending. I told him I wanted to speak with Edgar and he put me on hold for 30 minutes n connecting me with Edgar. I was going to come in
    today and start a phone plan with a phone, but I refuse to make a sell with someone like that

    Edgardo Marquina was exceptionally patient, knowledgeable and helpful.
    He is a stellar example of customer service

    Contrate mis servicios y me iban a mandar un gift card, me dijeron automáticamente iba a llegar a mi casa, que tardaba unos 3 o 4 meses el proceso nunca llego y llame para preguntar y no me pudieron atender , me dieron un numero de telefono y llame,después de 1 hora en la que me pasaron a diferentes departamentos me dijeron que no podían hacer nada , no podían generar otra, sabiendo que no la habían enviado, no cumplen lo que prometen.

    The workers here act nice and tell you what you want to hear but when you comeback with an issue they just give you the run around and toss you to the side. Zulemma told me the $30 activation fee would be waived if I call customer service. After being on the phone for 2 hours, AT&T tells me that they aren’t able to waive activation fees and to go back to the store and have them waive it since that’s what the promised. I go to the store and an employee named Justin tells me that the only person that can waive activation fees is his manager, however he’s off work that day which is understandable. Justin logs into my account, takes my information down and says he’ll tell his manager to get back to me. 3 days later, still no contact from AT&T so I call the store 4 different times and everytime I call the manager is “busy”. Horrible management. These people are quick to assist you and promise you everything when you walk in. But as soon as you have an issue they give you the run around.
