I’m using HDFC Regalia master CC for last 2 years. First year I used priority pass at India Domestic lounge for around 11 times, nothing was charged vs. promised 12 times free access.
Suddenly they change the plan without any specific notification(not even to such an active user!), no SMS(violation of RBI guidelines) and charged significant amount of USD 27$ for 4 visits during May - June 2017!
Request HDFC bank to reverse these charges immediately.
