I don't think they will end RSDC offers –
1) This is their premium card
2) This card is not easy to get, and usually comes with high AMC and with accounts of high AMB
3) Not all people with rsdc, are availing all vouchers
》OTT - probably everyone, once in a year
》GYM - only people from top tier cities
》SPA - only people from metro cities, lakme is another story
》TRAVEL - probably everyone who lives in city
》HEALTH CARE - probably the least used one
》GOLF - no one
》LOUNGE - since it was the most used and expensive(powered by PP) hence they devalued (which isn't bad)
The main reason RPDC got devalued is everyone was using it and many of us had more than 1 RPDC, some even had 30🤯 because it was really easy to get with very less amc some were even free !
But they can surely devalue some benefits if it goes above expected rates !
