Unfortunately we do not offer phone support.
We are a small team and we try to assist as many people as possible. In order to reduce waiting time for our users we only provide support via email. This also allows us to effectively gather all info we need (screenshots and screencasts) and provide all helpful links we might need to forward.
We encourage you to take a look at our help articles.
If you still need our assistance, we would be happy to answer any questions you have. You can find our contact form here.
