I had some problems using a database-type system at work and contacted the person responsibile for maintaining the program and working out glitches with my issue. Since she didn't answer the phone when I called, I emailed her the error message and let her know the circumstances for the problem.
She emailed me back with instructions for fixing them. I tried it several times and the problem still wasn't resolved so I emailed her back asking her if she had any other solutions. Her response: "Just keep trying."
I ended up asking some of the techie types around and got some suggestions and after some trouble-shooting, I was able to fix the problem myself. The solution happened to be very much not what she told me to do.
I emailed her back with details of how I fixed it and noted that "I'm not sure if I just didn't properly communicate what the issue was, but this is what fixed it, so if anyone else has the same problem, here's a suggestion for how to resolve the problem."
Her response was "If you have a problem with how I serviced you, please contact my supervisor."
I do not have a problem with how she serviced me, though I do think she wasn't knowledgeable enough to know how to fix this. From speaking to my other coworkers, this is a relatively common problem that they fix with the method that I eventually used.
I am now considering contacting her supervisor simply because of how she handled my suggestion for a possible solution when she's asked this same question again in the future.
At the same time, I'm unsure if it's appropriate for me to go to supervisor at this point, or if I should attempt to go talk to her in person first. This is not someone that I regularly work with and don't know her/her habits well at all.
