How would you professionally and effectively approach, without offending, a coworker (from another department - IT) who is supposed to help you, but is clearly unable to?
To name a use case, I am looking for specific approach (using well-established and frequently used software), in which the coworker does not seem to have enough experience. However, instead of helping me with that approach, or passing to someone else who can, I am suggested to try other approaches (such as using another not so convenient software), which would be time-consuming and ineffective for me.
Note that I am convinced the problem is easy to solve with the standard approach. All I look for, is a polite and effective way to be passed to another coworker who can help.
