I have written for a couple of the more reputable online companies and have never had complaints or issues from the clients they provided me. In fact repeat work from the same client was pretty common in the end. However, a word of warning, the quality of work varies considerably across writers, even in these better companies. I have witnessed some pretty shoddy essays from colleagues - but luckily QC would (or should) prevent them from being sent out. The problem seems to be the pay peanuts scenario - researchers are paid a little over 20 per 500 words (undergraduate 2:1) delivered in 5 days. Students get charged 2-3 times that amount. So the best case scenario would be to source a writer direct......Sorry not much help if you've already been scammed, but maybe this will help other students looking for help :)
