I called their all-Portuguese-speaking help office. One person, this time, was kind and got me an English speaker. I ranted about EDP, stopping to apologize to the person on the phone - that it was the company, not him I was so angry with.
The next day they sent me an email notifying me that my contract was canceled, but again billing me. I'm just ignoring their bill. I went through all my emails and have copies of emails I sent them, should they keep demanding money.
