Glen — cooktop stove - with glass

Address:

Thane, Maharashtra, 400610

I had purchased a glen cooktop stove with glass in aug-2013. The glass broke in dec-2018. So we enquired about the service centers and got one 'ankhad' service center number in bhandup, mumbai. We raised a complaint with the service center (Complaint # ak2294) and they promised to replace the glass. Its been two weeks that they are just postponing the date. The gas is still in the broken glass state (And dangerous?).

1. Need to understand if the service centers cannot fulfill the service request, why do they exist? Glen should take a note of this.
2. Very bad experience of the broken glass. Is glass cooktop a safer option??
3. If the multinationals cannot provide local service, why should they be authorized to operate in india?
4. The glen contact center[protected] just makes you wait for 2 mins and then asks you to leave a message. What is this helpline about? (Have called during the working hours only).
