This phone number is associated with a fraudulent debt collector. DO NOT under any circumstances give them any more information than they already seem to have. They claim to be attorney's collecting a debt but have no information on their client or want to release that information. They claim to be out of Dallas Texas but the SOS have no record of the company Zinco and Associates operating in Texas nor any other potential phonetic spellings. I phoned the entity they claim to be collecting for and they had not heard of the company.

FAKE DEBT COLLECTOR
