Caller name: Credence resource management
Caller type: Unknown
Calling on cell & landline. An person with strong thick Indian accent. Caller only able to identify my first & last name. Caller only provided Company name of credence resource management and that it was personal business matter and refused to give any more information about the nonstop harassing calls until I provided further information about myself & repeatedly stated for personal business matter.
Sounds like a scam and per research online shows that others found to be scam.
