Boat — Speaker is not working properly

Address: Imagine marketing india mumbai,Maharashtra 400093

I have purchased Bluetooth sound bar model no aavante bar 3500 vide invoice no FAN4GF[protected] and order ID is OD[protected] from flip cart on dated 25/08/2024.
all of sudden speaker got power supply problem display was missing. so I registered complaint no (CASE ID-IMRB-5TFVJ5-ELSYJN-CHU6) via boat customer care and they took a long time to only send technician name at home to check only actual condition.in between couple of times my case was auto closed and just informed via SMS without any solid solution.
after long period technician visited to just say that I have to pay Rs 2318 even warranty period is going on.
now this is worst experience shown by boat and I think they ask money without any reason
