Never ever EVER give more money until service is complete unless you want to give a tip. I'm sorry this happened, everyone is right about trying to charge back, I've won with friends and family payment before after being scammed. I did actually have to call them. (pro tip, if you do 0#0#0# when you get to the automated voice there's a strong chance you'll get customer service instead of dealing with the automatic service. Meaning you waste less time getting thrown around to different departments or dealing with different automated services.)
