BUY-DISSERTATION Never gets you an A+ or A (Post everywhere they don't refund on lower grades- Scammers)

i first got my essay written by buy-dissertation.com
i paid them for 1 page to check whether the work is original. i use to pay them for every one or two pages work. they delivered me my essay 12 hours after the deadline. not to mention that a percentage of my marks were deducted because of the missed deadline. now i will tell you about the paper. i didn't get any A or A+. they promised me that any grade lower than A means 100% refund. these scammers. they are destined to see their downfall because of their false promises. the lady on phone told me at least 10 times that they will return my money and my boyfriend's money if we got anything less than A. we got B and B-. they didn't return a penny. they are scammers. i will post everywhere that they are scammers. when they have PROMISED that full refund will be made on getting lower grades then WHY DON'T THEY REFUND. hopeless people they say they have already paid their writers for the two assignments. my one another friend also got scammed by their false claims. he too didn't get an A and NO REFUND. they talk big things. their manager told me our students mostly get good grades. we are 100% legit and our every word is our promise. they keep on telling our every word is our promise but they now don't refund. scammers, cheaters, lier, why get work done by them. never hire them. tell everybody STAY AWAY FROM THEM. can anyone please tell me how to get my money back. should i complaint to PayPal. i paid through paypal.
