NEDBANK ONLINE BANKING CALLCENTRE PHONE LINE DOES NOT WORK - NEDBANK TO PLEASE CALL ME BACK URGENTLY!

I have been trying to contact Nedbank Online Banking for over 2 weeks without success. As soon as I am transferred to the Online Banking callcentre from ********** 111, the phone call is cut off. Every single time for the last 2 weeks and without any explanation from the call centre line. I am trying to contact Nedbank Online Banking as a payment I made on 11th September 2018 using a bank-approved and registered beneficiary has been LOST and cannot be tracked. I NEED NEDBANK TO CONTACT ME URGENTLY PLEASE - THIS PAYMENT MUST BE FOUND!!!!!
