I run a web development company. I got a order from a USA client for developing 3 sites at 900 USD and got 300 USD as upfront payment.It is paid under service from the client We started working on the requirements one by one. We delivered designs for three and development too. Designs were changed many times and we completely worked with them for reasonably long period. There were no clear cut instructions from them,but we keep on doing our work to please them. All of the sudden they posted "Paypal Dispute" I submitted the evidence for the service and i won the dispute. But now i got a Paypal Charge back outside Paypal. How can i fight it ? How can i win this case ?
