ArdMoor review for Searchanise Search & Filter

We added this app to our store at the beginning of November, and although this app displays a help chat time of just 7 minutes for example - you regularly have to wait 6 hours to get a response. Extremely frustrating service - when nothing can be answered quickly. Also the app does not allow you to make bulk changes easily - so making changes to a large catalogue is very time consuming. If you have a large store with multiple variants - the 'in stock' filter does not work alongside the 'size' filter - which defeats its purpose surely??
