This is for Pass4sure.com, I have used your product for the 70-290 exam and I have to say that your product is the worst product that I have ever tried. I should have never used you guys to begin with. You state you guarantee me a pass but I have emailed and emailed you requesting when my refund will happen and you keep on just ignoring my emails. Well, I hope by writing this message other people will read this and stay away from your money back guarantee scam. Pass4sure.com is a scam and I urge everybody to stay away from this company. They have horrible products as well such as the 70-290. Waste of money!!! You scammers. read full review »
