Thank you & Goodbye, from Sanlam Gap Cover

I have been a member of Sanlam Gap cover since 2014, if I recall properly, just to find out that my membership was terminated on the 31st of December 2017 without any notice or communication. I found this out around mid February 2018, by me just phoning in to check on my policy. The call centre person informed me that it was cancelled. I then let her know that nobody informed me and I asked whether my policy could be re-instated...Unfortunately not as the cooling off period had passed....The matter would be escalated...We are in April now and still nothing!
