Card hijacked: ABSA and UTI Couriers

After a ********** transaction on my ABSA CC account, another card was issued to me, and ABSA had arranged for the new card to be delivered to me by UTI Couriers. About 2 weeks passed when I received an sms (on 30/03) from ABSA that my new card had been delivered. It hadn't. I'd neither signed for it nor laid eyes on it (despite UTI reassuring ABSA that the card had been 'dropped'). The next day I received two sms's, about an hour apart, from ABSA sending me a OTP to change the pin on that very card! Then I started receiving sms's that my cell phone number was going to be ported out to another network (which I obviously hadn't requested). Despite trying to stop this, my number was ported out at about 8pm on 3/04. I could only get my number ported back 24 hours later. Someone, presumably the holder of the card that had been entrusted to UTI, had access to my cell number for 24 hours, during which time 2 attempts were made to withdraw cash from my credit card account (on 4/04). This morning (5/04) 2 ********** attempts were made to access online banking using the number of the undelivered card. There is something negligently wrong with the security of ABSA's card delivery system.
