I have contacted both WGT customer support and the link provided by WGT customer support to address the problems with the offers made by Quiz Factory supported by Supersonic ads not following through with the credits offered for their quizzes. Every once in awhile they will follow through but the majority of time they are not fulfilling their end of the offer to complete their quizzes even when you complete 100% correct answers. Feel other WGT members should be aware of this inconsistency. Quiz Factory has not responded to my attempts to reach out to them via the supersonic link provided. argh!
