Don't take out Betterlife policy. ****py service

We have been trying to cancel Betterlife Insurance since October/November last year. Both my wife and myself phoned numerous, my wife has emailed them to cancel numerous times times and we get told its going to be cancelled or they going to call us bcak and they never do, but my account get debitted every month. Dont take out BetterlIfe, their service is pathetic. Looks like my only option is to go to the bank and try and cancel with them. Its over R3000 already they have deducted.
