ABSA credit card 3D secure issues

More than a month I have received my new Gold credit card from ABSA and I unfortunately I have not been able to use this card online for payments ever since. I Called ABSA 3D SECURE department almost every week using my airtime to report this problem and eventually I was told the cards starting with certain numbers have been blocked my VISA, this was 3 weeks back. No one could explain why or when this we will be resolved, no body seems to be taking responsibility for this, I have to keep calling every time!!!. I'm stuck with a useless credit card, cant book flights or pay for anything online let alone adding it to Samsung pay that also doesn't work. What must I do now WAIT!!! for what?? this is totally unacceptable service. The are other banks that are lining up to provide me with a credit card and I'm sure they can provide a much better experience than this. WHY MUST I STAY WITH ABSA?
