HDFC card 2X rewards on insurance

1.25 lakh customers first come first served. 25K minimum payment. Eligible from 15/03/23 - 31/03/23

Is the reward conversion ratio of 1 RP = 0.25p for the regular HDFC credit cards like MoneyBack, Millenia, Regalia?

Can someone share the effective cashback for paying a insurance payment of 50K?

Will it work on Diners card also...

Am I correct to understand? Since, RPs are capped at 1000 per customer, if original transaction itself is earning 1000 points, customer will not get any additional points by making the payment in offer period?

For example, if a Diner card holder makes the payment of INR 30k, it will yield 1000 reward points as per Diners reward program. What will be the benefit of this offer to Diners?

Is this a user specific offer?

Which is the best credit card for an Insurance payment of 50k...??

3.Qualified Transaction – ONE online Insurance payment of Rs. 25,000 or more between 15th March '23 and 31st March '23.

1.25 lakh customers first come first served. 25K minimum payment.

Terms are very restrictive.

It seems I have received 1000 points for this offer. Paid  LIC premium on Amazon via Regalia First CC on the 28th. Under unbilled transactions Amazon Insurance is mentioned. 

Looks like additional 1000 rewards points have been posted to the cards.
