Domino's Pizza — refund for 28th sept

Address:	751021
Website:	dominos.co.in

I'd ordered from dominos for inr649 (Order no 192). 5 items were ordered. 4 were delivered, that too 6min late and the 5th item forgotten and gotten after half hour.
Same day i called the customer service to raise the complaint. They said complaint registered and wait for 10 days to get refund. Its been 10 days and still nothing, all i have is a complaint number.
Recently, the restaurant manager calls saying i haven't registered any complaint.
This incompetency and unprofessionalism is unaccepted and would request for a result asap.
