Spice Jet Airlines — Ticket related issue

I booked a ticket for my father from my own debit card account from Abudhabi where i am currently residing .As my father wanted to travel from Pune to Kochi i booked the ticket from my own account.But during the time of travel the authorities of the concenred air authorities told some excuses regarding the ticket and they told as it was taken from abroad they need clarifications or else my father have to pay the fare again .As he was having the money that time he was able to pay the amount .
It is not fair that a senior citizen should not be troubled in such a way. If he was not having the money at that time what he will do???? This is really bad.Being a responsible airline you should not treat your customers in such a bad manner atleast to the elderly senior citizens.
I am really sorry to say that this type of attitude is really ridiculous.
The concerned Flight details is SG 185( PNQ to COK). PNR NUM ; BFKBSR.
