Stranded with no access to my funds

I am currently out of the country working under the United Nation. About month ago I forgot my internet banking password, which then required that I reset my password. To do this I had to put in my personal security details which included my ATM bank pin and that is where all my problems began because they ended up blocking my ATM pin stating the information I was giving was incorrect, I called and was directed as to how to reset my pin of which I did and it was reset a few days later. The problem sadly did not end there because according to me I was entering the correct required details which resulted in me having had to reset my ATM pin three times already because I was not properly informed that when I changed my gold cheque card pin that I was required to change my blue debit card pin as well, I was sadly under the impression that because the cards are linked it would automatically change my debit card pin as well which is the card I use for my internet banking thus when I put on the new pin it kept on blocking as it was still functioning under the old pin given to me by the bank of which I can no longer remember. I have tried solving the matter with the bank with no luck. HELP
