Travelstart is *********** - avoid

I made a booking with Travelstart on the 28th of March, and paid for it. For whatever reason, they did not reflect the payment on their side, so I immediately followed up with them. They asked for proof, which I provided, then they went silent. I have since not been able to reach them and have received a single half-****d response on one of my tickets asking me to be patient because their customer service agents are busy. For an online-only travel agency/booking platform, the fact that I have waited more than a week for them to get back to me with absolutely no resolution is unacceptable. They also absolutely do not respond on Twitter, where there are MANY similar complaints:

If you are looking to book a flight, hotel or car, look elsewhere.
