Airtel — reactivation of international roaming pack without consent after 6 months

Address:

560008

To begin with, i was travelling abroad in the month of april 2019 because of which i took an airtel international roaming pack on my postpaid number for 1499/- in the month of march 2019. It got activated once i landed in the said country abroad. When i had taken the pack, i was told that it will be deactivated on the 10th day irrespective of where i am.
I returned to india within the first week of april, which was hardly 5 days. I called the airtel customer service, where i was told that it was a one time charge and i do not need to deactivate it separately as the validity is for 10 days only.
In the month of august, during the last week i had to travel abroad and had a layover for about 2 hours in the same country. But i did not need a pack so i had not activated it. I had taken the day pack where i was charged 649/-. Later in the bill, i noticed that i was also charged an amount of 1499/- on the same day on the same number. Without my consent or knowledge it was activated and charged. I did not receive any text message nor email for the activation of the ir pack worth 1499/-.

I only got to know the charge was implemented when the bill came in on the 12th of september 2019. The bills are not available on the app "my airtel" either. I had to log in online thru my laptop and only then i could see the bill details. I called up the customer service where i spoke to ms. Saanya. She said that she has requested a call back to my number. Later another executive called me and said that i have to give the exact date and time for the call made for deactivation. I tried to reason with her saying that it is completely absurd for one to remember the details. I relayed my problem again and she says that i should have deactivated it she told me that they do not have a record for the call. If airtel does not have a record for a call made about 5 months ago, how do they expect me to provide such details!!

Being a "gold"member is an absolute hoax as this is the scenario of their customer care. Once i asked to speak to the manager, she goes on to inform me that i will have to call 121 and request thru the automated call. And that she cannot help me.
It is not about the amount of money but the fact that consent was not taken nor any information was given!!
I hope to see this resolved sooner.
