Rather than asking the company to cancel subscription remove there source of payment. If payment by credit card: Tell credit card company your card is lost and ask for new one. The new account number should
Stop renewal. Using a checking account: Ask bank for assistance. Good Luck!

Really devious. I tried calling and emailing to close and they would not help. I had to complain to my cc company. They, at least, understood, and they blocked harmony. Also, eharmony's greatly increased monthly rate... Again with no mail or email notice. A really dishonest, greedy company.
