Technical support?

Hello, I’m not sure this is where to ask, but I need tech support. I purchased a subscription on 22 December and have not been able to get my Google calendar to sync, which should be easy, but I emailed support@kalnext.com that day and still have not heard back (I gave it some time due to the holidays.) Would really love this tool; if anyone can tell me how to get support would be greatly appreciated. Sorry to disturb, and thanks in advance.
