Complaint Review: Netzero

I ordered Netzero mobile broadband January 8, 2015. The customer service agent I spoke with did not speak English very well. It was very hard to understand her. She sounded as if she could be from Trinidad or Africa. She asked me if I would use the mobile broadband at home or away from home. I told her both. She said that would be fine. She also asked me how I would use the internet device. I told her I needed it for online classes. She said that 2000 megabytes would be fine and sufficient. I received the mobile broadband device Janaury 12, 2015 and was only able to use it for two days for my classes. When I tried to log into the internet I was told that I had to upgrade my plan to 79.95 a month because I had used all of the data for the month. On top of that Netzero failed to tell me they were billing me for February January 12th, 2015 as soon as I set up the account. So does this makes sense to anyone else? I am billed for next month when we are only in the middle of January, and for two days only could I use the mobile broadband. I am going to advertise this all over the world. This is so wrong.
