Dismal after-sales support

I bought the Sony Bravia Home Threathre system and upon installation that not all speakers ans amplifier are working. I returnef the unit in 18 August 2026 after doing and following all advise on Youtube. Returned the unit in 18 August and have been receiving numerous excuses not to replace the faulty unit. They even stated that there was nothing wrong with sound system.

I said I will take the unit with exception that they have a rep to show the unit is workjng propetly, as it takes some time to set up the unit. I have followed up more than 10 times, struggling to get through and have sent numerous emails with proof.

When I call, I do not get through, tge after-sales support is dismal. I have not received proper feedback on the way forward and is driven to Hellopeter. I see I am not the only one complaining about the same thing. Can zi pleade have feedback, I paid a premium, but do not have access to what I paid for. Kindly advise as I had no option but to report it.
