First and last time!

I have always booked flights directly through the airlines themselves and this time I thought I would try Travelstart because I could easily book with different airlines and could just contact them if I needed to change the date or time of my flight. WOW, it has been anything but a pleasant experience! Little did I know what a mission it would be to try and speak to a human being and get some assistance. My BA flight from JHB to PE had been re-scheduled by the airline by 6 hours and so I needed to make another plan. This morning I waited on hold for about 35 minutes (after being told 22 minutes) when I eventually got through to someone! Unfortunately I was not given any helpful information. I was told to contact BA and they would re-book my flight; however when I called BA they said that Travelstart has to arrange it from their side. I feel like I am stuck between a rock and a hard place now. Their call centre also closes at 1pm on a Saturday until Monday morning!! I am now going to incur much higher fees to move my connecting flights because I can only sort it out on Monday, and I am supposed to fly early on Wednesday morning. This will definitely be my first and last time booking with Travelstart!
