What our customers are saying

  • 1 out of 5full starempty starempty starempty starempty star
    Manager and sales rep provided very misleading information. When called out about the lies they became defensive and told us to go to another store. Very unprofessional. Do not go here.
  • 1 out of 5full starempty starempty starempty starempty star
    From the reviews to what I actually experienced was drastically different. The store manager John and the sales rep Brandon were the most unprofessional employees I have worked with. They spent most of the time trading stocks in front of me and not actually helping. They completely lied about the plan and services we were getting and then refused to help after we contacted customer service. They force additional services and fees onto you without your knowledge. I would recommend to not go here and go to the cooperate store in Fairview heights. This is a retailer and work for commission. The more the up charge the more they make. Cooperate office is salary based and actually want to assist.

    The sales rep that helped me was not very knowledgeable and gave me misleading info. He did not give me discount as promised and failed to properly process my account. I was able to resolved most of my issues at a different location.
  • 2 out of 5full starfull starempty starempty starempty star
    The individual who worked with us was very friendly but upon receiving our first bill we realized that there was a lot of information that was incorrect due to miscommunication on the worker's part; despite us specifically asking the amounts and changes. We were VERY disappointed to find the charges and the fact that these charges were not relayed to us plus being wrong. Thankfully AT&T online was able to fix them but NOT before being charged for the month.
