Spanish Project

For my latest project, I'm supposed to call Guatemala, Peru and Chile! Dios mio, it's been a while since I spoke Spanish and I'm tyring to jot down a script I can rattle off when I try to call these countries over the next few days *gasp*

I can imagine asking the person on the other end of the line to please, please slow down, "mas despacio, por favor". I can understand Spanish as long as the speed does not approximate a machine gun and as long as the speaker avoid slurring too much.
