Not getting OTP resolved

<p>I have been out of SA now for 4 weeks and cannot receive my OTP via cell number. I have requested to change this to email. Firstly, the call centre agent never phoned me back to arrange this. Eventually after 2 weeks, and completing all the forms, I received a call from SA, stating that it was now changed from cell to email. When I tried to do a purchase online, Verified By Visa again showed my OTP was sent to my cell phone. Emerentia Ndlovu from the call centre is not responding, my personal banker is not responding, and after 4 weeks I cannot do on-line purchases. And I am suposedly a Private banking client. </p>
