Absa credit card division incompetence

I recently travelled overseas and before traveling I called absa credit card division to inform them that I would be traveling and using my card internationally, I was advised that a note was made and that I also could activate this function on my mobile using the app which I did. Upon my arrival in India , my credit card was blocked from making a payment 3 times. I then received a msg from the ***** line requesting that I respond confirming that it is indeed me making those purchases, which I did, my card was still blocked I then made 7 international calls to the absa card division and ***** line , I told them each time that I was paying for this call at roaming rates, the call was cut at least 4 times , then incorrectly transferred to the wrong person or transferred and then cut off. I’m disappointed in absa as I have spent money making calls to explain the same thing which was confirmed before I left SA. I also feel that absa should be liable for these calls made to them for their own incompetence.
