This old man is a registered pilot in FL, who bought an HSD Super Viper rc airplane at 750USD from us, but later he found a little problem in the item and asked me to help, i have always been helping and wishing to do something for him, but one day he retracted all 750$ from my paypal account by filing a case to his credit card bank by the name of retracting deal. I understand how worried a buyer is when he got a problem, but, he started to be mean, and didn't pick my tel and respond my tex message, although in the few months we made several calls and he promised me he wanted to pay, in the end, he want to play disappearance. This guy is a cheater.
