Sony India — Sony blu ray home theatre

Address:

Sri Muktsar Sahib, Punjab, 152107

Actually I purchased Sony Blue ray home theater in the month of December and service man installed it.But at the time of installation he said there is a problem in aux cable even we also purchased that one. And we called to service provider thrice but he doesn't listen and just replied will come tommorow and not yet came. We are facing problem as volume is not ok and even when smart TV is not in on mode and not connected to audio mode and also in mute mode buffer works. We called to this number{service provider- location malout -Ph no [protected] }.
kindly revert on [protected]-[protected] for this complaint as three months passed and we didnt get any service regarding this query.
