Double Charged

It's been 7 months trying to get clarity with my funeral policy premiums going off my account double, went to their different branches and everytime their consultants are giving me differerent stories and none of them could give me answers as to why I'm being debited twice every month. Last time I was told they have escaleted the matter to their customer care and will be contacted in few days to this day I was never called. I have tried several methods to communicate but I'm not getting through. Tried calling them and u hold for more than 30 minutes, sent an email but still no answer.
