Sony India — faulty mhc v21d

Address:

New Delhi, Delhi, 110058

I had purchased mhc v21d from vijay sales, dwarka, new delhi on 12 oct 2018. I had bought this system for fm & blue tooth facilities.
The fm in the system does not catch any channels. I had lodged a complaint with vijay sales and one expert from ace electronics services, rajouri garden visited us. After inspection the logic he gave was that our house does not catch any fm channels. This is absolutely astounding that a small transistor catches all the fm radio in the house but not this brand new sony system.
I think there is something wrong with this equipment which requires either repair or a change.
My contact details are given below.
