Cheap Car Rentals in Fairmount, Newark from C$ 7

I showed up. On time for my one day rental. They told me they had no cars but they would try to get me in a car some time today. No definite time, no alternatives. I waited an hour. Others had already waited two. I couldn't wait any more or I was going to miss my meetings. Had to cancel. Spent more than the rental amount on cabs getting there and back and was late for everything. One woman was helpful with a refund, but beyond that about as bad a service as you could possibly imagine.
