Airports Authority of India — Job offer

I was been called by number [protected] which might be still on to be called...
Then was told to fill up a form and had told to pay 2500-/ for form then I was interviewed by a male member of the association from [protected]. Within hours I was selected and the next they told me to pay 6500-/ for verification of documents and address I submitted the documents and the next day I got the verification letter but today it's 22nd June I'm been told to receive a offer letter from airline services through AAI recruiters and is being asked for 14500-/ till 4.00 pm and it's 1.42 pm right now. I researched about such frauds that have taken place before and I'm sure the same has taken place with me but I have cautioned myself right now and need to take a official action on the fraudsters.
