3 weeks ago, as a customer, I emailed a company's owner for help with a time-sensitive request unsolved by junior staff. 2 weeks ago, the assistant emailed me that she was ill, but intended to answer me. I still haven't heard from her. They didn't disclose her absence's duration, and asking seems too nosy. A cynic would venture if "illness" were a delaying tactic?
I don't know how to follow up tactfully, as I'd appear more worried about the difficulty than her health (with which I can't help anyways), even if I include good wishes.
