Tried to apply to use this as a payment option on my website, they sent a link to register but is expires after a certain amount of days. Unfortunately during that time, which the registering process was "open", I was hospitalized and ultimately it expired. I tried reaching out to them multiple times afterwards and have sent 4 emails explaining this asking if they could reopened the invite with NO responses at all. I even tried reapplying on their website, again with NO response.
