Vi — Postpaid Bill

I Purchased a sim card for vodafone Vi on 17 July 2021, the number got activated on 19 Jul 21,
I received a bill on 11 Aug 2021, stating that I had talked for 46 minutes on 51717 and they charged me Rs 600 for that
This kind of number doesnot exist when I tried calling it again.
Please take strict actions against this. I have proceeded to deactivate this postpaid number
These kind of things are being done and these companies have scopped so low just to extract money
