I read your post and watched your video with great interest so I needed to comment. As a former employee of Radioshack I have no love for this company and I was not present when you purchased your phone so I don't have both sides of the story.
I will say one thing and that it is not fair that you called the Sales Associates "Liars". Again I was not present when this happened but I would think that someone with your vast knowledge of cellphones, cell plans and contracts that you should have spotted anything unusual.
Then again the only thing that Radioshack is concerned with is selling wireless and sell it with accessories. In fact those Sales Associates who can not sell enough cellphones quickly find themselves on the Unemployment Line. I could go into what happens at monthly meetings, Conference Phonecalls, Emails sent from the District Manager but I am bound by the Terms of an Injunction set against my own website by the Radioshack Legal Department.
I'm not saying that there are those out there who lie to customers on purpose but your average Radioshack employee is honest, hard working and under a immense amount of pressure to sell certain items.
Again I have NO love with Radioshack Corporate but I do feel for the Store Sales Staff being I was an Assistant Manager for the company for two years.
