Just for info, in case you don’t know… the phrase “Have you tried turning it off and back on again” is (or at least originally was) a reference to British sitcom, The IT Crowd.

The show follows the IT department of a largish company and whenever anyone has any kind of computer problem of any sort, the advice given is to turn it off and on. Surprisingly this actually works most of the time.

So, I don’t think the OP was trying to annoy you, just make a pop-culture reference that they assumed you would get :-)
