Dear sir/madam: I had purchased my oven model 25sc3 on 9th may 2014, by the next day I even got the messagae from IFB care regarding the purchase of the microwave oven our executive will come shortly for the demo. But no one from till the date has come to show the demo and even the installation. Finally we thought of opening the oven after 3 months. Then I call to customer care regarding this though it was registered earlier no one has come for the installation demo, finally they have come 1 day back then I saw the voucher which was in the manual which is inside the oven so we missed our gift voucher worth rs4000/- as the last date offer valid till 30th june 2014. If I open my oven without their installation and presence it's one more problem regarding warranty they will say you opened without our executive presence but I waited no one come till yesterday since I don't know the voucher inside the oven as I didn;t open so .Now I need the gift voucher as it fault of IFB members it's not my mistake .
