“We’ve received your unsubscription request. We’re sorry to see you go. It may take up to 10 days to process this request” ^ WHY?! It took you 0.01 seconds to start sending emails at the beginning ¯\_(ツ)_/¯

If you keep receiving emails, just mark them as spam. They'll disappear from your inbox and will inform your email provider's algorithm that this company is spammy
I'd add that if the sender uses MailChimp, you can report directly to MailChimp for sending you emails after unsubscribing. MailChimp suspends accounts that have too many reports - I know this because our account got suspended for 3 days after we mistakenly emailed an old list
