I recently took their salary account in Nov. They opened it as treasures priority and there has been no call to show me any advantage on debit cards(I don't believe there is any reward rate on their debit card so why would I spend anything on it) + I haven't received any email with their ongoing offers(like timesprime, amazon prime etc) or the spend offer screenshots you provided. Their debit card page also lacks any relevant information and the tnC of the card.
One thing to note is their treasure's priority is a complete waste as they have divided it into treasures silver, gold, and platinum.. Having platinum or gold might have some worth due to some benefits but I wouldn't keep 30lac+ trv with them on regular basis since getting magnus burgandy with 30lac trv in axis would be much more lucrative.. I have not seen any advantage of having a salary account with them yet.
Only staying to get some credit card offer(like spark or vantage) and then would move to some other bank.
Is there a tnC page of the offers you shared in screenshot? like holiday package what's that or any more info?
Edit: here's the full tnC, looks like they put lots of ifs and buts for everything as always.. ---->
