Error in debit order that cost me charges

<p>I laid complaint on the Fnb website complaining about 2 paid unpaid debit orders even though funds were available in my account. No has gotten back to me even though it's been a week since the incident. </p> <p>Secondly I phoned fnb to change my OTP details but nothing has changed. I am still not getting my OTP via email as requested. </p> <p> </p> <p>I am disappointed at this bad service</p>
