exasperate - annoy
To ‘exasperate’ somebody is to irritate them greatly, usually by continuing to do something that upsets them. The word implies provoking a high level of impatience and frustration, and a sense of making something that is already bad even worse. It can also be used to describe a person’s vexation when their attempt(s) to solve something have failed.
