Marathon Administrative Co review: This company must be closed someday. 4 months and still no refund

The company Marathon Administrative Co was too persuasive and I finally bought their insurance. After some time I had a bad feeling and decided to cancel it. The agent was calm and told that they would return money within 10-14 days. I have waited and got some promises within 4 months. After all these months I lost all hopes to get money back and would be glad if someone would stop these people.
