It used to be 15 but in March I had it changed to 2nd of every month. (1st was not allowed).
Weirdly enough they didnt sent me statement of March 24, I also cant download it using mycards portal. it may be because of statement generation date change.
I maintain an excel sheet & I can see my total Feb spent for this card was 4453. about 90% of it was with select merchant. and I spent 607 for on dominos website for pizza. so maths still dont add up.
This all is getting too complex, specially now with missing March statement.
