Which general topic do you have
I signed up for a free account through tab but missed the activation email. Now the token is expired and my account is locked.
Is there anyway to get in contact with tab to unlock the account?
In addition:
Some mailproviders use spam-filters. So it also may happen, that the activation mail had been blocked or moved to junkmail/spam-folder.
Same might happen within your mail-client software.
