Lmao I have the same with AWS. I tried a free plan like 10 years ago, then noticed it was only free one month. On the last day I deleted and disabled everything, but I guess something took longer to deactivate because the next month I'm presented a $0.17 bill with a warning of account suspension if I don't pay up (like hell I would).

I still get those emails, twice a month. They go straight to the bin.
