HSBC — Asking for personal details like otp

Address:

560014

Dear team,

Today i got call stating they are from hsbc (From the number [protected]). As per them, they quoted that i have not used my shopping points and it is about to get expired. They would be converting that amount and processing that as credit in my card. For this, as a verification, they verified the card number and date of birth. Later, they started asking for the cvv number and when i denied, they said the message will come from the bank and to confirm that number.
The message stated "onetime password (Otp) for txn on card xxxxx5964 for inr 2468.00 is *." when i said this is confidentical, they were forcing me to tell that number. I disconnected the call.

Team: please verify if this is phising and if yes, please take action so that others do not get victim
