Collections Import Export Pro

Our company attempted to import 216 collections using "AP: Collection Import/Export". Although the import seemed to proceed without errors, only one collection remained in the end. The disappearance of the other collections is a major mystery to us. Moreover, we sent multiple emails to various email addresses of their customer service, but received no response whatsoever. This combination of technical issues and a lack of customer support makes this service highly unreliable in our view, leading us to not recommend it.
