Not transferring remaining account funds

After closing my Personal Relationship bank account with Nedbank, I requested that my remaining funds be transferred to my new bank account. The closure oc the accounts took place, however, several weeks later I am still waiting for the remaining funds to reflect in my new account. My former "personal relationship" banker has been of no assistance in this regard at all after several attempts to query the issue. I find this shocking. Nedbank has really left me with a sour taste in my mouth the last few months of service I have had with them.
