Before this one, your most recent comment on HN was written ten months ago, promoting your website. One person replied to that comment. This is what they wrote:

“I signed up on profilepicture.ai and paid, but have changed my mind before uploading photos. There is no way to contact you through the site for a refund because the live chat isn't working and there isn't a support email. Also, when I search the help desk no content is returned. How can I reach you?”

You ignored that person.

It’s no wonder you are getting lots of chargebacks.
