I had purchased a Refrigerator from Big bazzar, when there was a free offer of Koryo Microwave Oven along with it. Since they did not have stock at that moment i was told that it will be delivered with in a weeks time. Till date the same has not been delivered nor been contacted by them. I had visited 3 to 4 times personally but the response was the same. "We will deliver it with a weeks time".
Solution of your complaint
I would prefer to pay a little more extra and get a good Microwave oven instead of waiting for this basic oven with no feature or get refunded for the same
