Outsurance so called "Beat any valid quote"

So I was shopping around for insurance. Contacted a few places to check managed to get 2 solid quotes that beat the quotes from Outsurance. They advised that they'll pay between R500-R1500 if they can't beat your valid quote. So I emailed them back to call them out on this. Even after trying to call a few times I'm still sitting in a situation where I can claim that it's false advertising. They are quick to phone a person non stop, daily, to try sell you their services but when it comes to calling them or on their claims on musts hearts crickets🦗 in the background. Nothing... No reply. No fulfilling of their advertised claims... Not a word.
