Billed for a phone that was aupposed to be a free phone!!!

I encountered a similar issue. I was informed that I could receive a free phone (though it was a lower-end model). When my paperwork was processed, I had to electronically sign several documents. Unfortunately, I didn't review them thoroughly and signed everything, including one titled 'EQUIPMENT INSTALLMENT PLAN.' It turns out the 'free phone' wasn't really free. I realize it's my responsibility for not reading the document carefully before signing. However, at the time, I trusted a company like T-Mobile. After everything that has happened with companies like Boeing, I now understand that I shouldn't blindly trust any American company, regardless of its size or reputation.
