Unable to register credit card for internet purchases

I went to the branch to register my internet card for internet purchases. They basically give you a letter saying a will receive an SMS within 24 hours there after I have to go to a link but not within 24 hours of receiving the SMS. THe SMS is ambigous and I receive two separate with tow seperate codes. It mentions it not in the letter an activation code will be sent. But instead of being sent an activation code I get sent 2 Secure Codes in two seperate mails. I don't know which one is right. I wait well anotherr 24 hours as I got warned I will have to repeat the process if I do it sooner yet the process fails to activate. If you follow the letter it fails. Go back to the branch and they are clueless and they type in the Secure Code in the Activation Code. All they can do is repeat the process. That is another 48 hours + then repeat the process. The SMS gives no instructions what it is apart from it being a SecureCode. Yet Captic refers to the SMS as an activation code. In result is I can't use internet banking. My other bank wasn't like this but sends and OTP via SMS or email with every transaction. Capitec decided against this and only has one code for all translations. But problem is to obtain the code takes ages and the staff are lost in the process if I go to the branch. I play roulette at the branch in trying to register it. When you send an SMS send the instructions!!
