Utter Disappointment with Travelstart

I booked my ticket with Travelstart from Johannesburg to Port Elizabeth however I had to change the dates of my flight. I called Travelstart's call center and I could not get hold of an agent, I sent them an email and they got back to me within 24 hours stipulating that they will send another email within 24 hours with the penalty fee. I waited over 48 hours to get my penalty fee email quote and the penalty fee (R1314) was double my ticket, (which was R838) , already that put a sour taste in my mouth. It didn't make sense to pay a penalty fee that cost more than my ticket. I decided to cancel my flight completely and they took about three days to get back to me with the cancelation fee quote. Travelstart said that they will refund me R131 and it will take 6-8 weeks for them to process my refund which upset me to the fullest degree. I am thoroughly disappointed with Travelstart and I will not be using it in the future. Luckily my flight was a domestic flight, I do not imagine the frustration international flight customers will experience regarding their bookings and flights.
