Domino's Pizza — refund pending

Address:

40006

Domino's claims to deliver pizza within 30 min but in my case it was not delivered. When i contacted them asking about the refund they just sent me a ref no. Saying someone will contact within 24 hrs, no one contacted and my refund is still pending, been more than a week now. When called their helpdesk they just say will call u in 10 min, no one calls.
