Vistara — Unethical behavior and ill-treatment by Vistara ground staff

I flew from Bangaluru to Chandigarh on a UK-657 flight on 17th August 2022.
PNR was 5R2SHB. My check-in bag didn't come that day because they detected a power bank at the security check. I was not informed about the incident. When my bag did not come to the belt at Chandigarh, I started looking for staff around. I found a person from Vistara there filling up the complaint and other required forms.
When I asked him to drop the bag at home, he was quite defensive in his replies and denied. I agreed with him and as he told me to come to the airport the next day (18/08/2022), I went there around 7.44 pm after finishing my office.
After taking the bag I was exiting the airport, there was some issue, so I called Vistara staff back. I told them that I want to talk to the person who just handed over the bag to me, then a Vistara ground staff named Rishabh took the phone and started shouting at me. He told me that it's all your fault, we have given instructions already that the power bank should not be there in the bag. When I reacted to this, he told me that I am abusing him. What I know that these people are there to help customers rather pointing out at customers. I asked him who the hell are you to point at me.
I want to ask Vistara, every now and then there occur incidences where people do not get their bags on time just because of your staff’s mistakes. And when a customer does a mistake, so your staff instead of helping and proper guiding, points out at customer that it is your fault. What kind of policy is that.
After that, he kept shouting at me. I told him that I am recording this call, he replied my name is Rishabh, and go wherever you want to go and complain. I even told him that this shouting also comes under abuse. He did not stop. In the end, he told me in the same voice tone that this issue is resolved from their end and disconnected the call.
I want to ask Vistara what all have I done to deserve this mental torture and abuse. How come his shouting at a customer is not abuse, but a customers reaction is.
About power bank, I am educated enough to understand the policies, I knew it should not be in the check-in bag. But I did not keep it there deliberately. According to me, I did not have a power bank with me. I admitted it to that staff who was filling a complaint.
But that, in any case, does not give any right to any person to shout at me.
I am hoping that Vistara will look into the matter and will take action accordingly.
