Hello Krishna,
I completely understand the frustration about the store hiding your review. Our service involves collecting and displaying feedback on behalf of e-commerce merchants for their website. As store owners, they have control over what to display on their store's website so they are responsible for moderating their own reviews.
If you want to report this store to the e-commerce platform they are using you can do so here https://www.shopify.com/legal/report-aup-violation and they will further handle the
as they are better equipped to take follow up action about such issues.
Please let me know if you have any further questions
Krishna Ganesh
