Refund query

I requested a refund on the 17/09/2015 as i no longer use the gautrain. I filled the form and the lady said it will be in my account between 7 or 14 working days, it has been more than that.<br> I called the call centre where i was referred back to the station i filled the form and the lady gave me their head office number which i have been calling since last week. <br> A response on this matter will be highly appreciated
