Did you ever stop to think that a place like LKQ might infact be very busy?
Management prbably has many better things to do than talk with customers on the phone, unless you have a very ligit reason for talking with them.
Did you leave a message?
Have you tried email?
Has your temper possibly left them with a sour taste?
I belive you need to sit back and let them do thier jobs, leave a message, send an email, and chill.
Since you ask the question about core, did you do your research and find that 99% of all salvage yards have a core charge on engines and transmissions?
For someone who wants to throw the wieght of the legal system around for an aqusation of a "Shady" business, you really need to know what your talking about before you loose the case before you even walk out your front door.
Maybe the way you handle yourself on the phone with them is why you can't get anywhere with them, you probably ought to step back and have a look.
These people DO NOT depend on YOUR measely peance for keeping food on their table, insurance, and body shops do, you are a meniscule part of thier earning, and DO NOT MEAN SQWAT to them, if you flash any attitude or get crazy with the questions that they don't want to deal with you get thrown out the door.
OH! I'm sorry you didn't like that?
Deal with it, it's their business, and their rules, don't like it, go somewhere else, there is not SOP in the salvage world, they are not there to answer your question if this will work or not, it's up to you to figure it out, they don't have time for that crap.
Sorry if this is not the answer your looking for, in fact no I'm not, you need to lear that this is the real world, people like you who want to run around and sue people for your own lack of knowldge if futile.
I have my own set of rule you play by with me and how I do business, you don't like it, piss off, sue me? And the judge and I will see you back in court for wasting out time, while we laugh about it over drinks.
Get over yourself and grow up, learn how this works and quit being a girl about all this crap.
