Checked mails and saw bunch of newsletters from the same company.
Me: huh? I don't remember subscribing to these. *scrolled down* here it is, (button to unsubscribe from these emails)
*Clicked and got redirected to their feedback page before unsubscribing.
Me: Cool, just need to provide feedback, not a big deal. *gave feedback*
Message reads : DONE. Operation failed. Due to technical error

What!! I'm gonna block the shit out of you!!
