Sony India — sony bravia led tv panel

I have purchased Sony Bravia LED TV Model KLV 32R562C, Set Sr. No. 4518085 from Manisha Enterprises, Wardha (Maharashtra) on 14/11/2015 vide Invoice No. 867.
I have also purchased Extended Warranty for 2 Years vide EW Card No. 32033883 on 17/08/2016 from the service center Named Vaishnavi Electronics, Chandrapur (Maharashtra).
My TV has gone under repair for Display Panel for 3rd time, including the last time before 1 Month.
I made complaint to Service center, Their service representative came to me around 15th August and took photos from his mobile phone, and told me to wait for 7 days. I was in continue follow up with Mr. Satish from Vaishnavi Electronices, Chandrapur (Mobile No. [protected]). After about 20 days the same service representative came to my house with new Display Panel for fitting, but unfortunately, its connection plate (as said by the Service Representative) was different and once again said to wait for 2 or 3 days. and until now my TV is under repair for complete one month. I am complaining that your Service is very very bogus. There are very very negligent people in your Service Centre. I am very disappointed. Please do the needful at your end to solve my problem as early as possible.
