NutriVita review for Freshly Batch Inventory

I had used this app for almost 2 years. Everything seems working fine until i noticed that i had product expired that i was not able to delete the batch. Contact the support and for over 1 week they tried to fix the issue but then i got no answer and start noticing that i had other product with same issue. I have installed the app and now the expiration still showing on my store. I have contact support, again, and i hope they got back to me to remove all the codes. Expensive app that didnt work for my store!
