Blocked account while overseas. Told to go to a branch to fix the problem. How???????!!!!

So i have been overseas for almost a year now and absa blocked my access to my accounts (internet and app access) they sent me an email to pay for a credit card that was in arrears and said they would activate my access after. I did that and they still did not activate my account. I am now being told to go unblock it at a branch. How can I do that when I am not in SA? I have my card with me, I can verify my personal details. I’ve called several times which that by itself is costing me so much money for international calls. This is so frustrating!!!! I will stop banking with ABSA as soon as I go back to SA!!!
