KFC India — delay in refunding

Address:

Bangalore, Karnataka, 560010

On 31 st Dec 2017 I had ordered from kfc, I made payment through paytm, the money did not reach the shopkeeper, but the amount got deducted from my account.Then again I made payment through my debit card.I paid twice for my order.It's been past 10days my money has not yet been refunded, still how any days should I wait.I thought KFC IS A BIG COMPANY, but it's a pity that they can't maintain its customers properly.
