Bro, use it there is no way to increase the validity, its coded in that way only and you aren't modifying any points just whatever you spend they are dividing it by 150 and removing the decimal part and after that multiplying it with your card value like 5 for dcb/infinia & 4 for regalia. Every points earned in a month statement is attached with a date variable & if the date variable is equal to current month & year and year difference is 3, then your points will be 0 in this way its automated.
If you have the access to there code you can alter it by taking extra variable of type string, put in your Card last 4 digit & inside if just run continue.
Hurrah! Your points will never ever expire as your card will never touch there code of expiring rewards points.
Note :- for knowledge purpose only, anybody exploiting this must be punished according to law.

What happens if you book a refundable hotel 6 months into the future using points, and cancel after the expiry date? Do the refunded points immediately lapse?
