Dotsure Must Refund For R105 Bank Charges

I sent Dotsure several emails to pause the premiums until I can afford. I even asked them to confirm that no money will be deducted from my bank account as I'm currently unemployed. Instead they went and debited my bank account again last night which was unsuccessful and reversed by the bank and I got charged R105 by bank. They didn't even inform anything. You can't just go and debit peoples bank accounts as an when it suits after its been communicated not to do so. It's day light *******.
