Do not book with travel start

Travelstart has the worse customer service we’ve experienced thus far. My husband made a booking and less than 24hrs before his flight we receive an email that the flight might be cancelled or reschuled( not confirmed) we called the airline to no avail..they were just as useless, we then tried to contact travel start and have received no response. What is the use of having “customer service agents” who provide no service????…this has been a terrible experience with both comair and travel start, I do not have recommend booking with them!
