Sony India — complaining about my bravia tv repair

Address:

East Godavari, Andhra Pradesh, 533103

I’ve registered my compliant in the sony service centre on may6th that my tv had some horizontal lines with a job number-J81113863..They told that the panel wasn’t available but they’ll replace the tv..but the people in service centre won’t respond and the worst part is that the customer care number sony gives even they respond very badly telling that I’ll recieve a call back next day but i never get it..I’ve been calling them since one month it’s the same thing every day...i never thought a company big as sony would do this..worst customer service ever I’ve encountered ..compared to other brands like samsung and even MI is better with the customers
