Hello all. I just got a LG optimus phone with Metro PCS store. I had to choose a plan so I chose $40 plan. But the representative told me that I cannt go for a it I ll have to take the $50 plan. So I explained that I need the $40 plan so she said I can do that when I pay my second bill online. But I ll have to pay $50 dollars for this month. This can not be true, I think the sales representative is lying to me. Is it true ? If yes what should I do about it?
