Impossible to report Nedbank Card *****?

Unknown transaction "Internet Banking TransPO Box 6". Trying to report a ********** transaction on my credit card profile, either online or self-service terminal is impossible: - reported via Nedbank website and received auto-reply but nothing else. - phone card division. Card stopped and replacement requested. - transferred to ***** division. No answer. - Phoned ***** division. All consultants are currently busy. Message service doesn't work. - Through to card *****. Wrong department. It must be forensics. - Wrong department again. Transferred, but got put through to wrong division. - Call cut off. - Phone card ***** again. All consultants are currently busy. Call gets dropped after holding for 5 minutes.
