Longest Hold in the history of Call Centre

I emailed on the 22nd to cancel the funeral policy, but Nothing was done. I called them 3 times today until my airtime cut me off, called with a landline and waited for over 20 minutes and I still haven't received the help I need!!!!!! They are so unhelpful!!!!!!!!!!!! I want to cancel the funeral policy, it interferes with the DSTV
