Problem is that i got this notice (Your page is eligible for a custom URL) and as you can see above that my page URL now its some numbers, that's fine, but when press get URL, then google give me an option to add URL after this link
Re: Your page is eligible for a custom URL
Unfortunately the term 'custom URL' is a bit misleading. Google doesn't really give you the option to create your own URL - they only give you the option to accept / not accept a URL that they create.
If you do not like the URL that they create, then you should not accept it and wait for a (hopefully) better option.
If you wish to use the Google+ link elsewhere, and do not like the long list of numbers that are currently there, then you could use a service like bit.ly to create a smaller, more attractive link that re-directs to your Google+ page.
