Kutchina / Bajoria Appliances — Service not attended inspite of AMC

I've an AMC for my kitchen chimney. After making an AMC they don't bother to attend the service. I've booked for service over customer care number on 2nd February followed by reminder again on 14 th February. No one from Kutchina has contacted for attending the call. This is very sorry state of affairs going on in the service provided by a renowned company like Kutchina.
