Basically last night I was using my shredder for only the second time and it suddenly exploded and a spark lit the shredded paper beneath. This then started a small but rapidly burning fire and I ran to the bathroom and used the shower to extinguish the flames. At the time I was only shredding single sheets as it had been making a funny noise and I had used WD40 on the teeth section as per the instructions. I bought it in July last year but only used it recently, would you take it back? It was bloody terrifying and I did have a debate whether I should throw it out of the window or run to the bathroom.
