Verisign Premium Domain Check Request

I am using :

$conn->useExtension('charge-1.0');

for another registry works perfectly but for verisign I am getting error:

Call to undefined method Metaregistrar\EPP\eppCheckDomainResponse::getChargeForDomainName()

I think Verisign have premium domain support and why does not work this extention?
