My Ltf regalia gold got upgraded to infinia fyf because of 9l spend in 6months. Did I loose all my milestone benefits and points ?

I had significant spending over the past few months, including a foreign trip, so I primarily used my Regalia Gold card to work towards milestone benefits. During the April billing cycle, my relationship manager advised me to apply for an upgrade, given my spending pattern. I applied, and within a week, I received the new Infinia Metal card.

However, I’ve noticed that my reward points have been transferred at only 50% of their value. Additionally, since my Regalia Gold card has been blocked, I’m unable to redeem the milestone vouchers I was eligible for.

Is there anything I can do to recover the lost value or redeem the vouchers? I’d really appreciate any guidance or suggestions on how to proceed.
