The fact that you make your users contact customer support just to delete an account is terrible system design. There's no logical justification for doing this.

I do not see anything where you can delete your account but you can cancel your upgrade trial by going to:
your name (top right)
Premium (tabs at the top)
I just did it
I agree that users need the ability to immediately kill their own account when desired.
IS THERE A PHONE NUMBER TO CALL TO CANCEL THE ACCOUNT?
I need to talk to customer support about the 29.95 dollar charge on my credit card.
