Poor service

My wife admittedly made a mistake in booking our flights to England, she only booked one way instead of return, she contacted Travel start in Cape Town and was advised by Janine it's not a problem, and she gave the price of the return tickets. These worked out to be almost twice the amount she had already paid, my wife said that was ridiculous and was not prepared that amount. The flights would have been with Swiss air. She then received an email from a person called Ram, saying that a refund of R643 could be given, as she had paid R29,000 originally, and an acceptance of this would need to be received by 20th February or it would be lost. My wife contacted them and explained she accepted it was her mistake BUT the offer was unacceptable, the lady she spoke to said she understood and would " get back to her ", obviously because of this complaint no response was received, l then actually emailed Travel start with again no response received. Being old age pensioners this amount of money was a lot to lose, but even more so is the complete disdain by which we have been treated by Travel start, we cannot blame Swiss Air because we have no idea if they were even involved BUT we write this scenario to make people aware and be very careful of how Travel start conduct business, we will never use them again, as far as we are concerned they are not trustworthy.
