Hi,
We have purchased a koryo mixer in july month. And we have used it for about 10 times max and it stopped working. We need the refund of the money or please give the option to buy any other brand in same department where we have purchased. We dont want the replacement of same brand. Please do at the earliest.
We have given for service also and no reply from koryo. Please see to that issue will be resolved soon.
