Air India — air india took 4 times the money that was due

On may 12, 2019, i was travelling back to canada and my first leg of journey was bangalore - chennai. I would proceed from chennai to dubai and then on to toronto. I knew i had excess weight and was prepared to pay for it. But as soon as i got to the counter and as i was putting my checked bags on to the belt, a supervisor comes along and says to the person behind the counter - weigh everything and take money. The supervisor's name was gurumukh. After trying to reason with the man, who was extremely rude and disrespectful, i gave up and went to pay for the excess baggage. There were 2 young men behind the windows. I said that was there to pay the money for the excess baggage and he said it was an extra bag. I asked them to call the counter folks and verify it. They made some calls and said that the supervisor confirmed it was an extra bag and the amount was inr17600. Again, i tried reasoning with the men but decided to pay and somehow get out of there. I was paying by card and gave my card to the person behind the window. He keyed in the amount and then gave the machine to me where it said "enter pin." i entered the pin and he gave me a receipt. When i checked the receipt, the amount was inr71600. I was aghast and asked how it became inr71600. I ask to see their supervisor and the two men looks at each other and after some conversation in hindi and phone call to someone said that they would return the money. They take the card back from me and do something and gives me another receipt saying that the payment has been voided and the money will be returned immediately. So, i call the bank and they said that the money has been taken but it has not been credited back. I ask the 2 men why it is not credited back, they then say it will take 3 hours. The 3 hours has now become 8 days. Well, after voiding the invoice, unbelievably, they still take ask for inr17600. By then, i just wanted to get out of there and paid the money. I then went to see the supervisor (Gurumukh) who was no where to be seen but instead met with ravi. I repeated the entire incident once again and he apologized. I asked if they did not feel ashamed to take any money after having cheated me of inr54000.
I hate to say this but i think this plot to take money started with the officer gurumukh when he looked at me and said "weigh the bags and take money."
Is air india going to do anything about this? Does air india have any ethics? Is air india that corrupt?
