Appikon ‑ Back In Stock

The App worked wonderfully for a few months and then would send Back in Stock notifications for items that were out of stock/ have not been updated at random. I brought this to the customer service team and was unable to get a resolution. I sent examples of my stock history reports and compared them the the notification history dates, proving the item's inventory had not been updated. I was told this was impossible and proceeded to tell me it was my fault. I was very willing to work with the team and was given no response after 2 follow ups.
