That's really unfortunate and reminding me of How to lose your Bitcoins with CTRL-C CTRL-V, never forget to double check your address before broadcasting your crypto transactions.

When I look at the instructions on the page where we can buy copper membership, there is a warning

You can pay a one-time fee in order to increase the capabilities of your account. Be warned that:

You can still be banned if you break the rules. You will not get any special treatment.
These memberships are not guaranteed to last forever, or to offer the same benefits forever.
No refunds will be given.

Take a look at the bolded words so you only can request the admins and I hope theymos will help you in this.

I would hope "No refunds will be given" pertains to the account itself and not some accidental over-payment.
