Communication with Travelstart a nightmare

Communication with Travelstart is an absolute nightmare. We had to change a domestic flight, as info for another international flight (different company) came through late. Well, this was a total nightmare. It should only take me one phone call to sort everything. Instead, I had to go to a website and select an option. Then, a question will be answered (by e-mail - which I can not reply to) only a day later. Referred back to the website. Then, still not all information and I will have to ask again (on the website). After a week of trying to move the ticket (resulting in higher fees after the week), I saw the mail that the payment didn't go through? I was already in Cape Town and not always able to look at mails. In the end we just bought another ticket, which resulted in MORE costs, a lot of stress and frustration. PLEASE streamline the process so that you can make a phone call and sort things out immediately. In future, I will book directly at the airlines and will DEFINITELY not make use of this service.
