What teleport method should i use for a GLOBAL queue system

basically in my GLOBAL queue system after 2 players match they are teleported to a reserved server
thats cool and all but the problem is, these 2 players have a chance of queueing up with eachother at the exact same time causing 2 different reserved servers and teleporting them both to the reserved server their own server generated

this might be confusing, dont be afraid to ask what im yapping about rn
