Yes, a refund from eHarmony is possible.
According to eHarmony’s Terms of Service, yes, you can get a refund within three (3) business days of purchasing an eHarmony membership (excluding Sundays and holidays). You’ll need to do so before midnight of the 3rd business day, so timing is important.
To get a refund, send an email to subscriptions@eharmony.com, try using the chat functions to process a refund with an eHarmony agent, or mail in a letter to the company’s cancellation department. For eHarmony memberships purchased through the Apple iOS App store, cancellations and refunds must be processed through Apple directly.
Last, if you incur some form of disability that makes it impossible for you to use the service, contacting eHarmony directly in those scenarios can help you process a refund.
