R400 offer - poor follow up service

A MiWay agent called me on Friday last week to offer me a comparative insurance quote. He highlighted the fact that should he be unable to beat my current premium that MiWay would pay me R400. After spending 40 mins on the phone he acknowledged that the premium was significantly higher than my current premium. He requested that I send my current policy documents to a specified email address which I subsequently did. The automated response was that I could receive feedback within 72 hours. No one has contacted me since then. Is this offer just a hoax in order to get information?
