KFC — Delivery was not done. attitude of the representative is worse

Address:

Kolkata, West Bengal, 700017

Ordered food at quest mall kfc for an amount of rs. 598/- on 30/07/2016. After 25 mins they said that they will not be able to deliver in next 30 mins. Asked them to cancel my order since it was too late for delivery. They never said the same during delivery that it will take more than an hour.
Also attitude of the customer care representative was very worse. Seems that they do not know how to behave with the customer.
Very worst delivery. Worst attitude of the person.
