Pizza Hut India — Wrong pizza delivery

Address:

Bangalore, Karnataka, 560025

My son placed an order for a chicken supreme medium size pizza with chicken tikka toppings. What was delivered was a chicken tikka pizza. The price quoted for the original order was above 600 but the delivered pizza cost was only 500 odd.
Upon calling them again mentioning about the goo[censored]p, the service attendant said he would send over the delivery man to collect the pizza and re-deliver the actual order. I also told him that the pizza was for my son who was already quite hungry and to speed it up. He said he would. Now after waiting for over an hour there is still no sign of the exchange. Upon re-calling the service centre and asking to speak with the Manager, the new attendant Harish said that was not possible and argued back saying that the pizza ordered was the chicken tikka! After much argument, he said he would take a complaint and that I would receive a call back in five minutes, but clearly that hasn't happened either. So now my son is in tears and on an empty stomach...thanks to Pizza Hut.
