I CANT GET HOLD OF IWYZE FOR A QUOTE ON GAP COVER

I’ve been trying to get hold of Iwyze for two weeks as I urgently need a quote on gap cover. I’ve done numerous of “call me backs”, of which NOBODY has bothered to contact me. I’ve tried reaching out to them via Facebook and they’ve promised that somebody would call me back, I’m still waiting. I’ve also tried calling them and after all the tella prompts it goes to a voice mail. HOW ELSE CAN I GET HOLD OF IWYZE, this is ridiculous & unacceptable ?
