Unauthorized Calls from WhatsApp Business

I was duped out of two calls by a number from another country posing as a WhatsApp business account. +232 30 1254** was the phone number. I immediately filed a complaint about the incident using WhatsApp's feature that allows users to do so, and then I blocked the individual. On the other hand, I am concerned that someone may have gained unauthorized access to my account, and that my phone number may have been misappropriated or linked to obligations of which I was unaware. In the event that this occurs, I want to be very clear that I accept no responsibility for what happens. WhatsApp is solely responsible for any consequences that may occur.
