Who will fix the spin dryer on my twin tub?

I have a 2-year old twin tub washing machine, made by POLAR. Model no AGP 1231. It is still under guarantee, but the company are not responding to phone calls or emails. I think they may have gone out of business. The spin dryer has stopped spinning, though the washing part still works well. Who will fix the spinner? I live in North London.
