Sony India — complaint for tv panel replacement

Address:

Rangareddy, Andhra Pradesh, 500018

I had raised a complaint for my sony tv bravia ex-65 model dated 25th june 2017. Service center executive come and told me panel needs to be replaced. I gave my consent and it was told to me it will be done within 15 days.
I called customer care on 8th july 2017 and i was updated that because of gst it is taking longer.
On 14th july i called one more time and was told that service center will update me with alternate solution as panel is not available.
I called service center and they updated me that they are waiting for reply from sony india about alternate solution.
Till now i have not got any callback from service center and whenever i call them status remain same. (Waiting for reply from sony india about alternate solution)
Sony india has not provided any alternate solution to their service center till date
It's been 1 month i am following it without any progress.
