Ryobi Faulty

I bought a year ago a Ryobi belt sander and paid 799.00 for it then, it has been working great until it shocked the living daylight out of me and there was an electric fire inside the actual machine, I got such a shock. This is seriously dangerous, I don't have the receipt as it was a year ago, but I have googled that the product has a 2 year guarantee. I asked one of the staff there and they said that if I don't have a receipt they cant assist in replacing the sander with a new one. Im really disappointed as I have spent my hard earning money on this product and I do allot of DIY products myself and really need this machine to work again. Please can someone find it in their heart to assist me. The product still has its box and all is still in tact as I have bought it
