Account blocked and unable to return home

I lost my job early in Dec 2018 and I was unable to pay some debt. I visited some family in NZ and I need to come back. My pension fund has paid out and now my card has been blocked. I called ***and was on hold for 17 minutes before someone picked up. I was then told to call ***. I called that number and they said I should contact ***. I spoke to Anele that advised that I have been handed over and I should contact the lawyers to make payment arrangement. I called the number that she gave me, ********** and spoke to Lethal. Apparently they cannot pick up that I have been handed over. I spent 27 minutes on an international call to unblock my card without any luck. This is abaurd. How am I supposed to get back to SA if I cannot access my funds? Please contact me on my email address ********** as I do not have access to my SA cellphone number. I would like to pay my bills!
