What our customers are saying

  • 1 out of 5full starempty starempty starempty starempty star
    Worst service ever , I have been with the Bell system for 50 years, when AT&T was only long distance, thru all if it I have had great setvice. I am going with a different service for cheaper rates only. Friday the 15th of January, I went in to have my ohone unlocked, guy said 24 to 48 hours to have it done, I recieved text saying so. I went in today monday January 18th 72 hours later , I still have no phone service, I raised my voice and was thrown out by the supervisor. He threatened to call the police and have me arrested. Never had anything like this happen to me .

    If I could give this company zero stars I would. I never complain but I would like to share my experience with AT&T. This company is a complete ripoff, STAY AWAY !!!!there are better carriers, this company will juice up your bank account, and customer service line has no sympathy for you, all they want is to "STEAL' your money. when I first got my cell phone service in August with my own device (did not finance) I was told $50 a month + TAX according to Jaime my sales person. I asked Jaime twice " its $50 a month & it wont change correct?" he said "YES". Liess...... August $61.75, September $229.82, September again $99.55, October $50.66, November $81.10, December $169.20... lol "BYe". Remember my service was just one phone line and I did not finance a device.When I call Customer line 3 times to see what was going on with my billing, they always had an excuse for everything, none of their extra charges made sense. According to them I had the highest plan (Full Unlimited) one that I never agreed to.Even if I did agreed to full Unlimited so not worth it, went camping with my parents (they have Simple mobile) they had full service the whole time & I did not.$90 a month is not worth your time or your money. Its not an honest company, wish I had never made this mistake. Save your Money, their are a lot of honest carriers out there with better service
