NO HELP FROM ANYONE

I WENT TO GREENSTONE ATM TO WITHDRAW MONEY WITH MY GREEK AMX CARD. I DO THIS EVERY MONTH. AS THE MACHINE WAS COUNTING IT SUDDENLY STOPPED AND THEN WENT INTO TECHNICAL ERROR. I RECEIVED A RECEIPT STATING THAT THERE WAS NO MONEY WITHDRAWN. i RECEIVED AN EMAIL FROM MY BANK IN GREECE STATING THE MONEY WAS WITHDRAWN FROM MY ACCOUNT. I WENT ONTO THE BANK . NO ONE COULD HELP SAYING THEY COULD DO NOTHING ABOUT IT, THE MANAGERESS CLOSED HER DOOR IN MY FACE SAYING SHE WASNT SUPPOSED TO BE THERE TODAY!!! THE FLOOR STEWARDS HAD NO IDEA. I PHONED YOUR CALL CENTER AND WAS PUT TROUGH TO 4 DIFFERENT PEOPLE ALWAYS THE WRONG DEPARTMENT . I HUNG UP IN DESPERATION. I HAVE CONTACTED MY BANK AND THEY WILL SEND ME THE NECESSARY DOCUMENTS TO INVESTIGATE BUT I ASK YOU HOW CAN NEDBANK WHO WAS THE CAUSE OF THE PROBLEM JUST WIPE THEIR HANDS OFF THE MATTER, THIS IS NOT THE FIRST TIME IT HAS HAPPENED . THIS IS COMPLETELY UNACCEPTABLE
