Thepancard.com — Payment done but didn't receive my pan card

I applied for my pan card on 24th march, got notification for correction needed on 7th april.
As i needed my pan card asap, i informed them to discontinue the application process and give me the refund after deducting relevant charges. Because i have already applied for my pan card in offline mode and i also got my pan card within 2 weeks. But i didn't get any response from thepancard.com
And no further update of the application is there, they are not responding.
