Email from AVAST real or fake?

I no longer have AVAST since my new computer had virus protection already. I had previously bought AVAST. Now I get an email saying that my subscription is about to expire and they will renew it by taking funds from my bank account on May 6th. I am afraid to follow the link they sent because this could be a fake or malicious email trying to fool me. Can anyone verify this email and how can I contact AVAST to tell them NOT to renew my subscription?

I tried calling but there is no option to ask a question. Just support.
