You can submit a refund request within 3 days of purchase. In order to receive a refund, you must have used less than 10GB on the paid plan and it must be 3 days or less since the purchase. If it has been more than 3 days OR you have used more than 10GB of traffic on the paid plan, you are not eligible for a refund.
We urge you to submit a support ticket about any problems experienced before requesting a refund as most of the time, the issue is an easy fix.
