Poor customer service from gautrain

During the bus strike which took a month in April gautrain also suspended their bus sevices. Since i work at the airport and i use their services it affected me a lot. So i resorted back to driving. Then i logged a complaint about it and how it has affected me. Since i did not use their services for the whole and i already bought my monthly gautrain ticket and for their buses i asked for a refund. My refund was approved its over a thousand rands but its been 2 months i am being tossed from pillar to post they dont want to pay up my money. I call daily and i am now spending a lot of money calling. Pay back my money people i no longer understand whats the hold up from such a prestigious company.
