Book Budget car rentals in Puerto Montt

Cons: I arrived at 1830 at night to Puerto Montt, a small airport in Chile. I had a prepaid reservation, so got my luggage and went to the Budget counter. There was no agent there, but two "If you need help, please call xxxx-xxxx. I called the first number, and the cell phone was sitting on the agent's desk, not with him/her. So I called the second number, and a second phone that was sitting on the desk rang. So the agent didn't have either phone with her. I asked the agent at desk next door, and she said "the agent went for a cigarette break, and will be back in 10 minutes". So I waited. For 45 minutes, s/he never came back to the desk. Finally, I paid twice as much to rent a car from another company. Now, I'm having trouble getting my money back. What a crock of s*&t.

Cons: They ofer cars and dont have

Cons: GPS really is needed, or at least some detailed maps, as streets in the region are often not identified with signs. Google Maps saved the day several times!
