Deceiving Company - Freelance Translator Easytrans24.com Employee Review

I completed two translation projects for this company. Both were safely receipt and no further opinions, nor editing/revision was requested on their end. Two months after the first project completion and 45 days after the second project completion it was time to collect payment, but they told me my job was poor quality, just when payment was overly due. I was issue a PO for each job completed after a week of each delivery, which in their own terms, means there was a quality check on behalf of the end client, therefore payment is approved and I could raise an invoice. Of course, they no longer reply to my emails and decided to refuse payment not for one, but two projects, showing a very poor management and lack of professionalism. I was owed nearly $500 USD and I don't believe they will ever pay a dime. Just hope no other translator fall for this deceiving company.
