Wors booking management platform process ever

Booked a flight via Travelstart to Marrakech. Had to cancel due to family emergency. Tried to amend flight, ended up being quoted in excess of between 25% and 125% for the amendments. Eventually just decided to cancel. Whilst a small refund is now due to me (about 7% of the initial airline ticket due), the audacity to pay another R600 for the actual cancellation upfront and then only expecting to get the refund in 6 to 12 weeks (as per their message). I understand their role vs the airline, but the overall process is just to disjointed and I will never rely on a booking agency again due to the extreme poor customer service capability being a middle man. This is the 2nd time I have learned my lesson using a booking agency such as Travelstart, and needless to say I will never again book with them or any other agency. Most probably the worst ever reasoning received and explanations offered and by far the most unreliable booking management platform ever. If I never have to use Travelstart again, it will be too soon.
