We received an email reminder that our subscription would renew. The link to update payment info just went to the MDB homepage. The email says "Questions? Contact us at hello@mdbootstrap.com"... So I sent an email asking to cancel my subscription. I still have not received a reply. I was charged for a renewal. How do I get a refund?

Update: When posting this, a popup said to email contact@mdbootstrap.com about billing questions. Not to post here. When I emailed that address, I received an autoreply saying that address is no longer used.
