I got Axis ace in feb 2022 with a limit of 15k, I already had hdfc moneyback with 40k limit (now 80k limit) after axis ace I got idfc first with 25k limit in april and now I got icici apay card with a 150k limit. Now I want to get my axis ace and idfc millennia limit to increase but I don't have itr or any income proof cause my dad owns the business so I get salary in cash. Now is there any other way I can get limit increased in idfc millenia and axis ace? Like by showing statement of hdfc money back or icici apay that I have higher limits in them?
