It's not only for telecom bro , few days ago there is no charges.
But when I tried to book LPG gas it's showing me convenience fees 7.50 + GST on 830 payment 😕 They should consider for their co branded card , but they also charged for Ace. It's not good, somedays ago they also implant monthly 25000 utility bill payment is free, then they charge 1% + GST.
Make a calculation,
LPG bill: 829.5
Convenience fees: 7.5
Cashback ( 5%) : 41.5
Profit: 41.5 -7.5 = 34
