Does not honour guarantees on Speed Queen Washing machines as promised by Salesman

I bought a Speed Queen washing machine from Metro Montana. I had to choose between a LG and a Speed Queen washing machine. The Speed Queen was about R2000 more expensive than the LG and decided to buy the Speed Queen because of the 2 year guarantee that the salesman promised me. After 14 month the machine stopped working (really what you expect from a SQ) and contacted Metro. Metro contacted Speed Queen which informed them that the guarantee is only 12 months which is not what the store promised. Nowhere on any slips does it state the period of the guarantee or warranty is.
