Absolutely terrible. Will never use it again. I was charged for re-booking my flight that was cancelled back in March due to COVID19. Received an email the following day that the flight is cancelled. Called and they said they would get back, which they didn't. Called again twice after that and was hanged up on both times.
Instead called the airline directly and was able to change my ticket no problems.
Thus, these people are nothing but thieves. Not legit. Poor customer service. Zero stars.
