Is the R400 back a true advert or a ****

I was driving to work listening to Heartfm and heard the advert on insurance quotes. I sent the text to the designated number long story short I was quoted R1181.73 for car insurance and I advised my current insurer is at R581.94 so the call was abandoned and yet the advert had said if you can beat the customers insurer you then provide and move to you or you then offer to give R400 my question and complaint is on why this hasn't happened as I then received a call from Siyanda shockingly asking me sign up for the insurance which is almost double what I currently pay. I mean so is the false advertising or a **** to lure customers to you.OUTSURANCE Thank you for requesting a quote. Your reference number is ********** 9. An advisor will contact you.
