False SMS advertising.

I received an SMS on Wednesday promising me funeral cover up to R50000.00 as well as R24000 expense plus R10000.00 benefits from R86.00 per month. As it is much less than I currently pay for a much lower benefit I enquired about it. I was called by 1Life Funeral, who I currently am with. When I asked about going on to this plan I was quoted in excess of R220.00. I find this unacceptable and it is false advertising. Why do they not stick to their word?
