Sony India — Service Complaint not attended to.

Address:

Kolkata, West Bengal, 700033

I recently purchased television, which is not working.
I raised a complaint (no.[protected] on 30th August and was told that someone will come and attend to the problem in 48 hrs.
When no one came to attend to my complaint I raised another complaint (no.[protected] on 3rd September.
The service request was assigned to Neosa Electronics (P) Ltd. Phone No.[protected] / 40159525.
I also spoke to the person there but no help.
It has been 2 weeks and no one has come to attend the problem. My television is under warranty and this is unexpected from a company like Sony.
