Travelstart client service non existing

I had booked with Travelstart on an international flight. Due to virus situation I had requested a refund - numerous emails to their urgent line as well as customer service person since April 2020 and to date no response. Needless to say no feedback even after I had sent emails since the 1st to the 9th June. I don’t know what I am supposed to review as I have had no response to my request as yet. Service is really terrible and I wonder if they will even take note of this review as they know that people are not travelling at present so they don’t have to be concerned on this negative feedback. I would like to know if other people are experiencing the same bad service from Travelstart
