This Is How I Feel About My Cellphone Provider Right Now (or The Story Of Every Cellphone Company Experience Ever)
Today I looked at my bill and there was a $200 charge for changing my plan (to a more expensive one!). I needed more data and they don't have add-ons any more, which is the only reason I had to change it. Did it over the phone, and never once did the agent mention a charge. Nice surprise I get two months later!!
