Code Snippets not working

Hey,
i am using a hook for CF7 and it is as follows –
it add roles to user after submitting specific role , and if the user has that role it skips the process.
I have even tried doing some other processes with the hook but they dont work.
Code is as follows –
add_action(“wpcf7_posted_data”, “ccdit”,10, 1 );
function ccdit($cf7) { $wpcf7 = WPCF7_ContactForm::get_current();
if($wpcf7->id == 505) {
$u = wp_get_current_user();
if ( in_array( ‘verifiedcustomer’, (array) $u->roles ) ) {
//skip
}
else{
$u->add_role( ‘verifiedcustomer’ );
}}}
