they left a message that my phone number showed up on their phone and to call them back .

"Mrs Garber" left a message to call back regarding a 'time sensitive' matter.

I hung up on them.

Left message on my Dad's phone saying it was urgent and left a reference #. My mother looked # up on Internet and found it to be a bad #. She called and they answered phone as hello and not a company name. They will not disclose any infomation with anyone except who they are trying to contact.

by the way they called and left a message on my cell.

i just called them back beacause they left a message regarding my son giving them my phone as a contact.
the name they gave me it is not my son's.
i think they call (harrass) random people until they get whom or what they want, just because there names is the same or similar.

Sneaky sneaky. I almost called back! Not this time!

Its NCS, a collection company

when this person called what did they tell you? It said it was a urgent message, from a reference number or something.
