Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
It seems like you purchased the plugin with some other email address.
Can you please share the email address that you used to purchase the plugin or you can search and forward the receipt from FastSpring.com so we can locate your account?
Looking forward to helping you.
Thank you.
Hi,
I recently have been using the email address s*************@g******** for signing up on AI-related sites.
I suspect I might have accidentally created another account due to frequently using “Sign in with Google” lately.
However, for the payment of US$65.87 made today, I didn’t receive any receipt on either my main email S*********@h********** or the Gmail account.
Therefore, I’m attaching the receipt from PayPal.
I would be really grateful if you could refund the US$65.87 charged today and delete the account associated with s*************@g********.
Best regards,
Choi Jae-kwang
P.S
I couldn’t find a way to attach the receipt here, so I also sent a reply by email.
