That number belongs to Bernard Gassee Law Firm. They are trying to collect a debt. They will harrass you if you answer. Better to contact the people you own money to and arrange some sort of payment.
Remember, they still want your business and should be willing to help you out.
Received a call from this place today - they asked for me by my name. She insisted I confirm my birth date. I asked her what type of matter is it, she said "legal" - when I asked for more information she reverted back to confirming my birth date. When I refused she hung up. Scammers. She said she was calling from some law firm, unfortunately, I couldn't understand the name.
