Called twice today. First time I wasn't home and they didn't leave a VM. Second time they called, it rang twice and ended.
An Internet search on the name results in Mid Minnesota Management Services, a collection agency located at 2008 Veterans Dr, Saint Cloud, MN 56303. Main phone #: 320-253-8295.
This is a collection agency based out of St. Cloud, Minnesota. They are ruthless, unscrupulous, and I believe illegal in their handling of collecting debts.
