Refund And Guarantee Notes
The materials include a money-back badge. The window and conditions are not clear.
What We Know
A vendor-supplied badge says Money Back Guarantee, 60 Days.
What Is Unclear
The review page for the similarly named Nervolyn mentions both 60 and 180 days, and does not give reliable conditions. We do not know which applies to Nerveryn.
What To Do
Read the policy on the checkout page, take a screenshot, and save your confirmation email with the date.
If You Need A Refund
Contact the seller named on your receipt in writing, keep a copy, and act well inside the shortest window. If you get no response, contact your card issuer about a dispute.
