Not a good idea. Mods will not involve transaction that been made between members whether it's a good or bad experience. Leave a negative iTrader just like what nitinleew said. But usually when offering a services, buyers should pay first before they use your service and not another way around. - Dynashox -
iTrader ? If he has 200, do you think he gives a *** for -1 ? He should be banned, and if the transaction is made via PayPal just launch an investigation. And yes, first you pay and then you get the product. Or pay 50 % before and the other 50 % after the job is done.
You can start a thread about that person! i hope it can affect to his next business or you can give him Negative Points!
If you have exhausted every other avenue then I would make it public. How did you pay? You can charge a dispute with paypal. You can do a chargeback if using a credit card. G
If its the script,then don't deliver the script to the buyer. Else you should leave the buyer negative itrader to let the next person dealing with to be careful.
