Titanium Credit Card Issues

I obtained a Titanium Credit Card from Absa about 5 months ago.<br> <br> About 4 weeks back I wanted to pay for classes online, but the card declined my purchase and said there was something wrong with my account and I should address it immediately. I called the support number, which transferred me to several departments and I ended up at the Secure Code extension. After giving them all my details and explained the situation, they said there was nothing wrong with my card/account and should just tried again. It didn't work.<br> <br> I called them about six times without any solution or help. They were friendly, but no resolution could be given.<br> <br> This happened later on two separate occasions where I needed to pay for something online, and I went through the same procedure. The latest was when I tried to buy airplane tickets and my card was still \inactive". This escalated to me having to ask someone else to buy me tickets and having to pay much more and instead of having a 2 hour 50 min stop-over flight"
