this number contacted my son via his cell number asking for me, we do not know who this person is what so ever

Said this was last warning call for my fathers property.  That this was the last voluntary call. Before they take legal action .SCAMMM

Possibly an lawyer or collection agency, trying to contact my ex.

They called10 times today saying they are making a legal complaint that I was drunk and they would not say who they were saddd

Definitely some sort of call service. You can hear all the commotion in the background... They called and harassed my receptionist trying to speak to one of our other employees. Kept saying that they were on their way to our office every time they called back. Called 6+ times throughout the day. Receptionist started sending the calls to me instead. Once the caller realized I was onto him all they would do is just hang up. Very shady...
