An appliance repair company I used exactly once maybe 5 or 6 years ago recently started spamming me with texts and emails trying to get me to refer friends to use them or use them again. Never hit the "report spam" button faster.

I'd kinda understand it if they had sent me a polite text or email shortly after our initial engagement saying "hey, if you had a good experience please review us/recommend us" but coming in literal years late with a blast of multiple messages screams "we hired some sort of marketing firm and fed them our customer database".
