MORE THAN 2 WEEKS FOR A REFUND

ITS BEEN 15 DAYS SINCE I WAS PROMISED MY REFUND FOR AN OVERPAYMENT DONE AND I AM STILL WAITING. I MADE A IMMEDIATE INTERNET PAYMENT THAT WAS DUPLICATED AND THEN NOT REFLECTING AS A PAYMENT. I WAS ADVISED BY THE AGENT TO PAY WITH MY CREDIT CARD TO SECURE THE BOOKING SO i MADE A 3RD PAYMENT. LATER IN THE DAY WHEN THE IIP'S WERE PROCESSED. I CALLED THE AGENT AND ADVISED HER THAT NOW GREYHOUND WAS PAID 3 TIMES FOR ONE TICKET. SHE ASKED FOR PROOF OF PAYMENT. I SUBMITTED AND SHE CONFIRMED THAT I WILL BE REFUNDED ONLY WITHIN 7- 14 DAYS. I STILL AWAIT MY REFUND AND ITS 15 DAYS.....
