Even I am facing the same issue. My renewal is in December 2024 and app is showing 15L but Burgundy customer care is saying 25L spends are mandatory. So I am thinking to close off the Magnus or convert it to Atlas or Reserve.
@fradela That part is done and getting standard replies from them.
I have even approached X handle, Let me see for the timeframe mentioned by all, 30days and will approach RBI OM.
