Breana...you weren't necessarily overcharged, you're paying what's called a "charter price"...they go where YOU want to go at an agreed upon rate.
A route cab is similar to a bus system...cheaper, set fee & anyone along the "route" shares the ride.

What a wonderful opportunity...staying with your family for a couple of months! If you're part of the Archway family...you're pretty much related to everyone in the West End!!
