Log and Jotter support?

We're 4 or 5 months into a multi subscription for my family, but my son's subscription did not arrive this month. It's 10 days since my wife and I received our subs, so at this point I've given up waiting on it. I've emailed the "support" email for them, but much like when I tried to reach out at the start about multiple sub discounts, I've gotten absolutely no response. Is there a better way to contact them, or is this just normal for this company? I rather like the product and the gimmick of it, but if the company doesn't support it at all, I'm inclined to end the subs and cut my losses.
