Freelancer has STOLEN funds from me, making multiple significant ($100+) charges to my account despite having not authorization or cause to do so.
After having to dig through their site for nearly a day to find how to "request a refund" it took 17 interactions, 5 extremely clear demands and two whole weeks to refund the money... MINUS A DAMN TRANSACTION FEE!
On top of that, every single entry I received for jobs I posted were blatantly plagiarized from google images. I even had one guy from India literally copy my job posting, word for word, post it as his own for a lower price, in an attempt to make money for himself. He intended on making someone else do the work for my logo job, and sell it to mew for more money! Freelancer apparently believes this is ok, as even after reporting it they've never responded.
Multiple other people I have contacted who've used this site have have had the same issues. My wife and her business partner used the site at roughly the same time as I, and had multiple erroneous charges appear on their account, and have yet to be able to get their money back.
