You have already signed the message several times... but the problem is that you keep making screenshots, instead of copy/pasting the text from Electrum into your email message to Freebitco.in support??!?
Why do you not use "ctrl+C" and "ctrl+V" to simply "copy" and "paste" the text from Electrum? You just need to highlight the text and use Ctrl+C and then Ctrl+V when writing your email?
The "standard" format for a signed message is:
-----BEGIN BITCOIN SIGNED MESSAGE-----
Message here
-----BEGIN SIGNATURE-----
Address here
Signature here
-----END BITCOIN SIGNED MESSAGE-----
So, copy the "Message", then copy the "address", then copy the "signature"... you should end up with something that looks like this:
-----BEGIN BITCOIN SIGNED MESSAGE-----
On August 5, 2019, I registered an account and sent a deposit to 1CCzSWVkvMikWboDtAxq6An9XQivYYgrJn, in the amount of 0.01340200 BTC.
When registering, I made a mistake when indicating e-mail. I indicated [email protected], and my current email address is [email protected].
As a result, your letters go to an outsider, not to me.
-----BEGIN SIGNATURE-----
1CCzSWVkvMikWboDtAxq6An9XQivYYgrJn
IHvtc/VsFeYnVhGitYEWPyfgwP3F0+cnibksMwGYsYZnFNYriuYfmRc8v76f+ZnESwb0zczl9HpuuHHJEY72io4=
-----END BITCOIN SIGNED MESSAGE-----
NOTE:
This signed message IS NOT VALID. DO NOT use it. You have too many hidden "white spaces" characters in your message that make it impossible to work out correctly from your screenshot... so I cannot get it to verify with the displayed signature. Try not to put any leading or trailing spaces at the beginning or end of each line.
Again... You need to
copy/paste the info from Electrum, and put it in your email to Freebitco.in support!
Well... That would certainly explain some things
