Great Eastern Trading — dusty tv & remote missing from the brand new lg tv package

I have purchased a tv lg 43lk5260 led from baruipur great eastern trading co. West bengal on 9th june 2020. I wanted to delivery from uluberia branch as my permanent address is near uluberia because my parents stays in bagnan near uluberia. Due to this pandemic covid19 lg agent told that the installation would be late so i have gone bagnan and tried myself to install the tv because in the pandemic situation tv is the only source of entertainment for my old parents. While i was opening the package, i found that the tv was not rapped and remote was missing, the pouch that contained tv remote and tv manuals were opened and also the back side of the tv was too dusty. It looked like i have purchased 2nd hand tv not a new one. I called the baruipur branch and the lg agent who had sold me the tv completely denied that missing remote is not possible, lastly they agreed that the remote might be missing and they told me to talk to the uluberia branch manager.
Today i talked with manager of greater eastern trading co o[censored]luberia, the manager was very rude and he told me that i am fraud and my family members are also fraud. I myself had stolen of thrown or hided the tv remote and was telling a lie after hiding the remote. They told that i cannot afford a new remote. I got the delivery of tv on 15th june, the lg agent denied to come home and installed the tv due to covid19, my parents are alone in home as i stay in kolkata so they couldn't installed after the delivery. I reached there on 24th june and tried to installed it myself. The uluberia manager told that why i had installed it. I have stolen the remote myself. He told me why had the package been open without any lg representative and actually lg agent told me in this pandemic situation the installation will be late so that i myself opened the package. The manager totally denied the dusty conditions of tv and missing remote.

After buying this product should i keep it as a mile stone??? No one not taking any action on behalf of lg electronics and great eastern trading co, uluberia branch... Really its a harassing matter for me. I want to replace the tv as it one kind of defective as it didn't contain it's original remote. Please take action asap.

Thanks & regards
