Insurance company

Hi Guys so last month as in November 2017, 2 ladies came to my house and explained this insurance thing and how it works including the Funeral cover, it was so interesting due to the fact that don't have medical aid, they left sim card with me and I have parted my number, I then have received my airtime as promised by after 2 weeks which id yesterday, and after I have also called them..so now on the 15th Dec the debit order came through but was like how because I gave the last day of the month...so now am reading these complaints am so concerned and worried as it looks like they don't keep their promises as mentioned..I even called Santam just to check if this company exists because am worried, but waiting for their response they seem to be lost about this Unlimited.. they will do an investigation and am going to withdraw my application if this is a ****...
