Airport to Hotel transportation

We booked cancun trip(11/10-11/15) through Orbitz...recommended Gray line Airport/hotel transport...arrival to canun airport no problem.limou. waiting for us(2), rose given to my wife.At the hotel I inquired about greyline to confirm return day&fl.time at courtesy desk.somebody there told me that the Rep.for gr.ln. not at the desk.So I left a note...returned back every day twice..no luck till the day before departure at last there is a person behind the desk.Vrey rude, hostile attitude when I talked about my repeated attempts claiming tha I should've shown at the day of arrival 5pm. at the desk, , dont know why!!!probably he promoting some trips or merchandise..that we wer'nt interested in.Then came the main issue Re.confirming transp. for cancun airport...he will try to ?accomodate us..but no guarantee because of that...the thing that outraged me &I left the desk in anger..till A decent lady emerged from a nearby office accompanied me she called Grey Line office?Headquarter (George) confirmed the reservation&advised me to file this complaint . Day of departure..delay of arrival for the limo.!!!driver miscommunicated..thought we stayed atRoyal Solaris not Grand S.!!! W.F.Aziz-clearwater Fl.
