ARS calls from multiple deceptive phone numbers and they do not leave messages. One came up as a place called Highlandpark? Whatever. They've been reported.

No message left. They also use the following numbers: 800-909-9095. Get and sue their butts.

Associated Recovery Systems is a division of ARS National Services.
