I am srinivasan.. I bought a koryo micro wave on 23sep.. It's already one month over after they said they will come for demo..
I want to return this product and i promise i won't ever take another koryo product and will tell all my friends and relatives not to waste time on the koryo products.. Bcz of they can't even come to give demo i am 100% sure they won't come to repair in case o[censored]nserviceability..
What warranty and such non-sense, i have called them so many times.. But they have stopped attending calls also..
My number is [protected] & i live in mathura cantonment
