HDFC Bank — receiving marketing calls despite of dnd activated

In order to stop receiving telemarketing calls from HDFC bank, I have activated DND through HDFC bank portal multiple times and last one was on APR 12, 2024.
Despite of DND activation, I keep receiving marketing calls for personal loans, credit cards and other sales related calls everyday from HDFC representatives. Sometimes I receive multiple calls from different numbers and I have to attend, respond and block the number. Since the calls come from personal number(look alike) I have no options other than attending the calls. So it seems HDFC bank is not taking DND seriously and not sure if there is way to stop such atrocities.

Most recently received calls from below numbers: It looks like personal number. But I have no choice other than posting here for proof.
