Is Punta Cana Fast Track legit?

Hello,

I know there is a VIP service directly through the Punta Cana airport via https://www.puntacanainternationalairport.com/en/vip-services but is the Punta Cana Fast Track (https://www.puntacanaairportvip.com) also legitimate? I just put in a request for the one through the airport but I’ve been told it is likely sold out but I won’t know for sure, which can take a few days. If they are sold out, I’d like to see if this other service is available.
