Net Zero Net Zero is a complete fraud Internet

I bought a 4 g internet plug from Net Zero, after seeing their ads on TV. I was told that I would get a strong signal. I plugged it up and got red lights flashing, which was suppose to turn green. NOT!!! I left it on over nite, still nothing! Call service support, told them what it was doing. Called me back after 3 days and said I was getting strong signal. Then said tower was 4 miles away!!! No I am not getting any signal!!! Called support again, this time I was told to go outside and use computer in yard. What! What! No I will not go outside to use computer!!!!.I paid $24.99 for piece to fit into usb on computer. then I paid $19.95 shipping and handling, which now they do not want to refund!!! and the monthly charge of $8.99 which was prorated. What they are doing is ripping people off!
