cancelation to ABSA Life Insurance

I have sent a cancelation to ABSA Life Insurance to ********** on the 1 March 2018. I tried to phone them on the 05 March ***to find out if they had received the email. The problem is that I was on hold for more than 25minutes twice and only got to the automated voice recording, I could not even get a consultant and eventually had to hang up as it took to long. All I wanted to know is if they did receive it and what is the current progress, I will never do anything via ABSA again.
