POST OFFICES CLOSED DOWN AND NEED MONEY PAID INTO BANK ACCOUNT

I URGENTLY NEED A CONTACT NUMBER OF SOMEONE WHO IS IN CHARGE AT THE USELESS FACILITY CALL GEPF. MY GRANDMA IS 80 AND THEY STILL DON'T WANT TO PAY HER MONEY IN HER BANK ACCOUNT. ALL THE SURROUNDING POST OFFICES CLOSED DOWN. THE NEAREST ONE SHE HAD TO PAY A TAXI R600 JUST TO FIND OUT THERE IS NO MONEY AND THEY OWE HER 5 PAYOUTS!!!! I AM AT A POINT WHERE I FEEL I NEED TO SPEAK TO HIGHER POWER. IT HAS BEEN GOING ON FOR 4 YEARS NOW......PLEASE HELP ME TO HELP HER. PLEASE PLEASE WE'VE SENT THEM ALL DOCUMENTATION A FEW YEARS AGO AND AGAIN THIS YEAR BECAUSE APPARENTLY SOMEONE IN THEIR OFFICES MISPLACED THEM. STILL UNTIL THIS DAY THEY DIDN'T EVEN ACKNOWLEDGE RECEIPTS OF THE SECOND SET SENT TO THEM IN ORDER TO PAY THE MONEY IN HER BANK ACCOUNT. THE BANKS ALSO CLOSED DOWN IN THIS TOWN SO WE HAD TO JUMP THROUGH HOOPS TO GET THE FORMS SIGNED THAT THEY SO BADLY WANTED TO DO THEIR PART, YET NO LUCK.....I DON'T KNOW WHERE TO GO FOR HELP AS THEY DON'T ANSWER PHONES OR EMAILS!!!
