OnePlus India — Complaining against unknown practices used in a Oneplus authorised service center in Brigade road

I had purchased the OnePlus A5 model mobile handset via Amazon.in website on October 31, 2020. It was working fine and this was the highest price mobile that I had bought investing more than Rs. 15, 000/- on a cell phone. I live with my aged parents in the most troublesome neighborhood ever known in the world(Marappa Layout, Raja Rajeshwarinagar). My mobile fell off accidentally while I placed it on the seat of my bike and a few scratches started appearing from the top right-side to the bottom on the main screen. A few days later without my knowledge, the phone ringtone was muted which could not be set right again after several attempts. Strange things keep on happening to our household and known people visiting our house who have never ever done anything wrong even by mistake.
People are unduly taking disadvantage of the Corona pandemic in the city and are playing cheap, dirty tricks at will. I have even approached the police, raised several online complaints to our safety and security. Once the unlock news was spread, I found time to venture out to correct things back to normal, my first step was to call the nearest authorised service center in Bangalore. All the available phone numbers from the contact center answered by female voice were busy after 10.30am. I then spoke to a lady voice claiming to be from the authorised service center at Richmond circle who told she can get me transport to get the mobile serviced to and from VR mall at Whitefield which I flatly refused due to my personal and my aged-parents safety and security, not to risk their lives either. I suspect the authenticity of this call as it seems to be pre-planned to make me the sacrificial scapegoat, to further the ongoing problems faced by me and family.
With no further ado, I decided to visit the center at Brigade road and saw a long queue all the way to the road at the building. I was told by the security that it would take at least an hour from 2.35pm to get inside the service counters section. I waited and as I received the token number, went through the grind of waiting on the hall, I could sense the ill-minded treatment meted out in many of my earlier companies that I had worked for in Bangalore. The seats were with proper cushions but very uncomfortable, cameras all around, unknown strangers claiming to get their mobiles serviced were let in, people trying to fool you with bad temptations, little quarrels arising out of nowhere, lady staff(mostly 90%) inappropriately led and managed by a bunch of fools over the center all making me feel uneasy. I wasted my time until 4pm investing my valuable time, energy, money and everything with the hope of correcting my mobile faults only to be told that the mobile set is not a real one. It is a refurbished set and would require Rs. 8000/- to be repaired.
I can see a major involvement from many of the so-called big companies and their misdeeds arising out of out-of-world tactics, practices being present there and would request a thorough investigation to nail the culprits and their hands involved in trapping me in this heinous crime. With the onset of Corona virus appearing near completion, it becomes very, very important to take strict, severe action against them after the pre-independence era to show no mercy in meting out the strictest of the punishments. I would require a new mobile phone handset to compensate for this huge loss incurred by me. While I try to complete this complaint, I am still being forced to think about the troublesome neighborhood making unknown number of 'n' number of noises known only to the devils lying in a graveyard. Everyone involved in this should be punished and taught a lesson of their life before proving their existence on planet earth.
This is one of the several complaints that I have raised on internet platforms and would prefer an email response only on resolution. My personal mobile number is [protected].
