premium version still not working.. and they won't respond to fix or refund!!

we were using the free version of this plugin and decided to pay to upgrade and get the premium version that is supposed to include ways to automate the backups. it took about a week to receive the download files but they did not come with any instructions on how to install.. and i have tried everything i can think of to add or update the plugin with the premium code and it’s still not working. i emailed them for help and still haven’t heard back. we paid for the software on 8/4 and now it’s been 21 days and still nothing to show for our money. bummed.

update 9/9/15: i’ve emailed them twice for help getting the premium version to work and received no reply. i emailed asking for a refund and no reply. now i have to refute the charge on my credit card.

beware!
