BoostMyGrades boostmygrades.com BoostMyGrades is not a tutoring site, they are cheaters Internet

I needed some help in my logic class.  I felt the logical thing to do was find a tutor to help me.  Boostmygrades.com promised results, they told me they had the best tutors around.  They had master degrees and PhDs.  I sent them my class syllabus and they said it wouldn't be a problem at all.  I sent them $800 which sounded like a lot, but they said they would help me out with every assignment and test.  

They then asked for my username and password, which I didnt like at all.  They explained that they just go on the site and do the assignments and tests.  I could not believe it.  They arent tutors at all!  They are cheating liars.  I want to learn not pay someone to take my class for me.  I tried to call them to get a refund, but they would not answer.  They wouldn't respond to emails about a refund either.
