ABSA: h0649 combi card has prohibitive holds

I recently received a credit card from ABSA. The process of acquiring it was easy and the assistance I received from the lady at the call centre was great. When attempting to link the account to my app, I received an error message. I called and another assistant said I should do it online instead of on the app. I then received another message: h0649 combi card has prohibitive holds. I tried to use the card for a small purchase as I was advised to activate the card and it worked. I did not receive an sms however or anything to state that money was taken out of the account. I would like to sort it out so that I have control of the account.
