not sure what todo

I'm an RA ERP and I keep getting sent to truck stops. I am not diesel training. I have recieved less then 2 hours of training and have 0 overnight training and I was told by a supervisor that I was getting taken off of truckstop list. Yet I keep getting sent put and it's genuinely starting to get on my nerves.because they know I don't know what I'm doing and refuse to remove me from this list. Should I call the personal manager and discuss this. Because I despise being sent here with a passion and never want to be sent back if given the choice.

I just don't know why they both refuse to train me and refuse to take me off the iesel trained list.
