boostmygrades - boostmygrades.com They told my teachers and now I'm EXPELLED. Internet

I needed some help with an online class. After a quick google search I found these guys.  They told me I had nothing to lose and that I could sign up and give them the assignments and then I would receive a quote.  Well after giving them all of the information the quote was absurd, but what choice did I have.  I really needed help.  I felt pretty safe considering the fact that they let me pay them after the assignments were done.  The scam really began once I paid them.  

They asked for another $300 then they originally quoted.   I told them no.  They threatened to tell my teachers that I cheated.  I paid them the extra $300.  The next day they said they would need an additional $100. I decided to come clean with the school and fail the class after spending all of that money on the course and these horrible ripoff scammers at boostmygrades.com
