Why Rain fooled me

I cannot believe that I was fooled! I got such a friendly phone call from a Rain consultant and she assisted me so nicely with correcting my invoice but now my billing is ridiculously high and I've sent 6 emails to Rain with no response. They cut off my internet because I don't want to pay the amount they want me to pay I'm disappointed and now im stuck with no fixed source of internet. I am disgusted.
