Travelstart service poor! Prohibiting me from making further flight changes with Qantas! 3 weeks later and still no results!

During the first week of July I wanted to make a change to my booking with Qantas which involves splitting a booking and amended my date. My wife will make the returning flight alone with our 3 children (toddler and 3 month old twins) and my mother in-law will fly from SA on the same flight to assist with the kids and have a bassinet assigned to her seat. Because the in-law booking was made with Travelstart, Qantas cannot assign the bassinet to her seat. The request needs to come from Travelstart. I have spent 30min plus on several international phone calls during the first week of July to make the request with Travelstart, but no one could assist me. They recommended I email Travelstart. I emailed Travelstart on 9 July explaining the situation very clearly with all the relevant flight information of all parties involved. I have received automated feedback emails on a couple of occasions and now I am just being ignored if I request feedback on this matter.

This is the worst service I have ever received to which should be a fairly simple and mundane task. The email said they will respond within 24 hours. From 9 July until this day 25 July I have had no concrete feedback or progress on this matter. This lack of attention is currently prohibiting me from making any changes to my booking as Qantas is awaiting Travelstart to make the change on their side before my booking with Qantas can be split and changed.

I have always been an avid fan of Travelstart and have booked most of my flights through them over the years. Regrettably this time was the last time!
