Curt,
I'll throw my two cents in here on how you might escalate it. About 10 years ago I had a tape backup drive for my computer fail in warranty. It needed to go into the service depot to be repaired (replacement was not an option) Due to some internal logistics (moving the repair depot to another location, someone was on vacation, we're too busy, whatever ....) I got jerked around for a week or two and through a number of people ..... none of which appeared able to do anything EFFECTIVE about my situation. Additionally, I was met in at least one instance with blatant conduct which, to put it mildly, might be considered not real good PR (public relations) The situation looked pretty hopeless (I needed the drive asap to restore some data) and I was getting pretty pissed.
So I found out the contact info for the corporate offices and called and asked the name of the CEO (even better if you can get his/her name prior to calling - say off their website)
I then called again later (to avoid being filtered by the traffic cops) and (using my best professional business execfutive manner) asked to be connected to the office and secretary for Mr. X - just like he and I were old golfing buddies. Once connected I explained that I was trying to send a fax to Mr. X and did she have a number that would go directly to him or would definitely result in him seeing it. She gave me the number and told me that indeed anything that I sent in he would definitely see. (Incorrectly restrticting incoming communications to an executive can be a dangerous thing for a lower-level person to do)
So I wrote up a letter, as the owner of one business to another, and basically told him the problems I was having, the incompetencies of his junior personnel, and then informed him as business owner and consultant who recommended his products that based on my experiences that there was no way I would ever be able to recommend them in the future. The letter contained some degree of ridicule (basically "what the heck kind of operation are you running there ?") although it was fairly well couched so as not to offend the CEO personally - but it was plenty plain enough so that he got the point (with a bullet /forums/images/graemlins/shocked.gif )
Within an hour after sending the fax I had a call from the CEO's secretary explaining that by the following day they would be sending out overnight to me a brand new tape drive and would I please return the old defective unit. Her manner in the call was so grave that it prompted me to ask her if my fax had caused much of reaction. Her reply was that yes it had - and that a number of people were now looking for new employment as a result.
The bottomline on all this is that if whoever you are dealing ain't getting the job done you have to BYPASS THEM BY WHATEVER MEANS YOU CAN, and get to someone who can do something about it. In almost all cases the CEO can - and he/she might well appreciate you contacting him/her - the individual may be desperately trying to figure why some company problem exists (sales are on 12 month downslide) ..... and not have a clue what the real reason is.
