On the 21 August i received an sms from my bank that African life debited R850 and was regected due to insufficient funds. Fistly i never did any quote with them and i dnt have a policy with you. Now my account has a rejected debit order fee and my account is in arrears. <div><br></div><div><em>(Supplier name changed from African Independent Brokers to Unity by Hellopeter.com)</em></div>
