[US]Anyone heard of the "Merchant Services" scam? And if so, what are they trying to do?

A business receives daily scam calls from individuals impersonating 'Merchant Services' to request sensitive information about a non-existent merchant account. Callers use spoofed caller IDs and attempt to deceive employees into divulging details, though no legitimate account or personnel exist. The scam appears designed to exploit potential vulnerabilities through social engineering.
