Sorry for the delay guys. Didn't think my sorrow would create so much excitement
I spent a few lacs on FB/Google ads. My understanding was that as I have my current ac with them and all payments go through it, its pretty valid as it all falls under the same customer ID. But I don't think axis is that chill. They had asked me to share invoices for FB ad spends for last few months. Hadn't shared that with them as I saw no point.
I have friends who spend much higher amounts with other banks and haven't faced any issues. Weird ax-is would want to lose a customer who's paying their card fees + pays bills on time + has current ac and investments with them.
