Worst insurance bank !!

I regret the day i join standard bank,i dont even wanna explain how the made me took this insurance every month they debit double the premium plus its always the wrong debit date, after noticing this i stopped it and emailed to cancel the policy even called several times they're still debting twice the amount..when i reverse and stop this debit order it still goes just today they debited twice ... Angry is an understatement of how i am towards standard bank im livid!!! I want my money back !
