LG Electronics — Unethical behaviour, unreasonable and no customer support

I purchased LG G8X from Flipkart on 17/10/2020. After 12 days I am facing switch off and on issue. I contacted Flipkart they asked me to approach lg service. I called lg service. They have given their local service Center phone number. I have contacted them and they said they won’t provide support as they don’t have kit to open my phone and asked them to take my phone and register complaint and send it to Chennai, where service available. They said this is not their duty and they are not responsible. After that I contacted lg service. They have again given Stephen, Lg area service manager, Madurai phone number. Initially during conversation with customer support he said phone will be fixed in Madurai and he will direct Trichy customer support to take my mobile and send it to Madurai. Later he directly called me and asked me to come to Madurai and he wants to share a phone number of lg customer support, Madurai. Finally I agreed to come to Madurai, which is 120km from Trichy. However, he didn’t send mobile number. Next day I called him. He didn’t pick up and after one hour he sent an mobile number of Raul, Madurai service Center. I called him and he said in Madurai also kit to open the mobile is not available and asked me to talk to Stephen again. I called him and I asked him to talk with Raul and provide a solution for this issue. Later after 3 hours he sent a message to me and he said Raul will call me and he will direct me. One day is over again no support received. I called plenty of times to lg customer care and they said they will forward this complaint to technical support. But it won’t happen, it will take at least 2 days and they won’t provide fixed solution to resolve the issue and they will ask me to visit Chennai in this covid-19 period. I don’t know what is the use of lg customer support in local areas. If they don’t have service at least they can accept the complaint and they can forward it to other customer service Center. But nobody is responding no one is taking responsibility. Kindly help me in this regard. It’s almost 7 day, I didn’t receive any proper response from LG.
