Outsurance R400 dishonesty

Outsurance does not live up to it's own word, the switch and save campaign they are currently running is proof. Last week I went and got a car insurance quote with them (as they advertise everywhere) and they couldn't beat my current insurance premium (matched like for like). As per their advertising I expected them to honor their word and pay the R400 instead they sent an SMS saying they will email a link that will have further instructions THEY DID NOT SEND THE EMAIL OR LINK. So I called in to do a follow-up still nothing, and I'm not the only one who has experienced this.

How can I trust them enough to ensure with them when already they are being dishonest. Not a good experience at all.
