Query: regret buying this rice cooker

i regret buying this cooker because after a year, the rice starts to stink after a day. it gives an awful smell on the rice that you won't be able to eat it and just throw the rice in the garbage to waste. i don't know what causes the smell, i tried cleaning it but no result. it doesn't even go with the costumer service number info. i have to buy another brand because of this.
