Travelstart Misleading customers

I also think that the Flexi date option offered by Travelstart is very deceptive and misleading. I was pleasantly surprised when I was initially quoted R90 to change my outgoing flight but unfortunately was unable to take it up at the time and did not confirm it within 24 hours so had to send a new request for date change a few days later. The second time I requested the change I was told the shortfall would be around R7000! I was told that that was the " difference in airfare" from when I purchased the ticket until now. I went online and saw that the same ticket actually now costs less than what I had paid initially so how on earth can I be paying for the difference in airfare? Based on my calculations they should pay me the difference! The explanation I was given is completely ludicrous and misleading to say the very least. I am now faced with requesting a quote to cancel my ticket to see if canceling and rebooking an altogether new ticket will work out cheaper. This makes no sense to me at all and the additional payment for flexi dates is a complete farce. Travelstart should be ashamed of this practice.
