Sony India — TV

I have lodged a complaint for service inca[protected] and have been provided with the name of the service center as nri electronics ghaziabad. i am the owner of sony tv model no. kd-49x7500f. the service center is not only anti-customer; they are a sort of extortionist as well. after getting the initial inspection done, they informed me that the mother board needs to be changed as child components are malfunctioning. i told them i would get back to them. i later informed them to send the motherboard at my place, as i will not allow them to take the tv, basis their poor online reviews, i was told it will be done. the owner mr. tiwari and the service head mr. shukla asked me an advance for the motherboard which is something awkward to me. the service centre which is not responding on calls, can take away my money and may not respond. i request sony' which too is not responding on social media or on thier webpage to please respond. i will have no option now but to use the public platforms like mouthshut.com and other such platforms, apart from using public complaint platforms floated by government of india, including consumer forums to demand service to my tv which the service centre is not attending. i also need an alternative service provider other than nri electronics.
