Don't post your email address in plain text on a public forum, mate.

And you do need to contact support. Nobody here can do anything to help you with that, only GOG support staff can.

Here is the form you can use.
https://support.gog.com/hc/en-us/requests/new

Select "Account and Website".

Sorry, I've only got Waaar Suppooooooort....

.... but yeah, do what ZFR said. The GOG staff must be smart enough to see that gmai is clearly wrong here.
