So my petrol was stollen out my car last week sometime

At first I thought it was siphoned out through the gas cap, but when I went to go fill up over the weekend, petrol started spilling out all over the place... A hole was cut in to my fuel filler pipe! And for those who do not know what that is - it's the pipe that runs from the gas cap next to the wheel well in to the petrol tank. This little 1.5m pipe to replace new with labor would've been about R1600, don't even get me started on the cost for the temp fix, aka duct tape! Managed to get a pipe from the scrap yard though at a much cheaper cost!
Now this is where my real gripe comes in, the guy at the scrap yard said that I was the 6th customer that they've had within a span of a week to get the exact same part for the exact same car! Now what prevents it from happening again? Does anyone know if you can get flexible metal pipe to slipline over the plastic pipe?
EDIT: It's a Hyundai Atos.
