Girias India Investment — girias rt nagar. not caring for customer

Address:

Bangalore, India

I purchased one ifb microwave oven (25sc4) from this girias show room at rt nagar, bangalore, but after sell on 12 sep, till date thay could not arrange a demo/installation. I called the store manager over phone several times but she is not bothered to listen to me or give me a feed back.
I called ifb customer care many times but their customer service is also not so much bothered about the customer, they talk so arrogantly and not giving any consideration to a senior citizen.
I now assume 1. I have done a great mistake by purchasing a product from girias. 2. My mistake is i opted for ifb product whose customer services are not at all good whereas while purchasing girias told me that ifbs cs is very good which is not proved to me.
