Olx India — Too many promotional calls in a day from OLX Autos

I entered my mobile number yesterday (30/05/23) at around 11 pm to check a listing for a used car. Today (31/05/23), since 09:56 AM till 01:29 PM I have received 9 calls from 9 different numbers all belonging to OLX. Even after telling them I don't want to be called and disturbed.

This is the call log.

This is just harassment. Please take a look.
I have already blocked these 9 numbers, but they keep calling from a different numbers.
