They call three or four times a day and leave messages every single time. They also make it seem as though they are a local company with a local phone number etc. but I believe they are a collection company trying to collect on a relative of mine. I have told them it's not even his number etc. and block their number but they continue to leave messages.
called this am, left message to return call to Global Services, do not know who they are or what they want. Next time they call, I will answer with "United States Marshall Services, Mail and telephone fraud division, Oklahoma, How may I help you" and see if that puts a stop to them.
