I called back number (08) 8253 4108 spoke to a guy who said I've reached Compare The Market.
March 25, 2019
Caller: Compare the Market I was using their site for online comparison's at 8AM. Received a call from them at 8:30AM and then again at 9:30AM. Although their T&C's state "I agree that comparethemarket.com.au or it's partners may call me during the Call Centre opening hours, and email or SMS me, about the services it provides.", I wasn't expecting such a quick response. Must be struggling for business.
