Unwanted WhatsApp Calls and Messages from Unknown Numbers

I am being continuously harassed by unknown foreign numbers through calls and messages, and I am absolutely fed up with it. I refuse to take responsibility for any potential data breaches, unauthorized access to my bank accounts, or similar incidents. The responsibility lies with WhatsApp. The numbers causing this disturbance are currently ‪+22350502282‬ and +62 838-5866-758. I do not want to receive any calls from numbers I don't recognize. Unfortunately, there is no option in the settings to address this issue, and there is no customer service unit that I can reach out to for assistance. Therefore, I have decided to share my complaint here, as I have no other means to voice my frustration and seek a solution.
