Credit card delivered to mailbox outside my gate

ABSA contracted DSV Mounties to deliver my credit and garage cards. DSV mounties JHB call centre agent contacted me on 1st of September to confirm my delivery address but also asked me if I had a lockable postbox. I requested that they should deliver my cards at home as there is always someone at home but phone me prior to delivery since they could not give me the precise date and time of delivery. Unfortunately they did not bother to contact me but instead on the 6th/7th September they left my credit cards in a post box outside of my gate(not even lockable). I contacted ABSA premium banking on the same day (around 17h30) and spoke to Ashwin. He contacted DSV mounties and spoke to Seshnie/ Cheridee? about the incident whilst I was on the line. She denied the practice but promised to follow it up and so did Ashwin. He promised to call me back the following day after he had followed the matter up.I was mortified by the occurrence & practice but up until today Ashwin nor anyone at ABSA has ever contacted me back. ABSA clients consider yourselves WARNED: your sensitive information can potentially be left at your doorstep with no care. How does ABSA consider that premium banking practice?
