Poor customer service with no response

I had a life; dread disease and disability policy with sanlam. My premiums were abt R 1500.00 per month which became unaffordable. I chose to cancel my policy of more than 5 years. I had sent thru a cancellation letter in mid February and received an email acknowledging my cancellation. On the 2nd March sanlam debited my account for an already cancelled policy. This has put my bank account into arrears; i have lost every single cent of my contributions as Sanlam has not given me a cent back like other insurance companys should you cancel my policy, furthermore they have debited my account and refused to refund my premium. I have queried it and the excuses i had was that it takes 28 days to cancel; shocked and disgusted as this is the only company that takes this long, asked when i would receive my refudn; no date was given as they need to inform my broker first and then make sure the money thats already in there account does not get refunded to me by my bank!!!!! No logic and has to be the height of stupidity. Never received a response already 10 days later after my complaint. Please people dont ever take policy with Sanlam if you do not understand the **** what you about to get
