No feedback from Travelstart

I give Travelstart so much business as I book all the travel for my company and yet it has been so challenging for them to get back to me after weeks of logging a request. I have logged 2 requests for the same issue on an existing flight and called twice and was told that I will receive feedback via email but to date still no reply. And when I log a ticket on line I dont get confirmation or feedback. What is happening with Travelstart?
