no matter if complete milestone or not, you will be charged for annual fees of card as well, so be ready for that too.
chances of vouchers are 50-50.
Simply click Milestone vouchers are sent within 2 weeks to one month of completion of the milestone..
If not received u can call customer care and ask them to send/resend the vouchers again..
PS: vouchers only sent through SMS..
I spent some amount towards milestone spends of 1 lakh, but now it got reset to 1 lakh🥺
Then which bank's cc r good ?
They stopped sending me this vouchers long time ago 
this cc or sbi are not worth your time
