I have ordered pizza at 3:20pm on 20 june 2016.
I have made payment of around rupees 1550, with paytm gateway. the amount got deducted, but i didn't get any confirmation from pizza hut. than i called customer care service to ask about my order, they said that the order is placed and it will get delivered within 1 hour. but again i didn't get any email or message, so i called again and again but got same reply. at 5 pm i got a call that my pizza is on my way, i have waited for half an hour for the delivery guy, than at 6:25 he came, and said that your total amount is around rs. 3100 and you have to pay it now to get the pizza (12 pizzas now but i have just placed order for 6 pizzas). i said that i have already paid it online, just give me 6 pizzas, i have also showed him the mail confirmation i received. but he refused to give pizza, as told by his store manager. than i called customer care for this issue, thrice and every time they have put me on hold for 15-15 mins and told me to call back, but they didn't. and finally on the last call they said, that they will refund my amount and will drop me an email regrading the refund. but as usual they didn't.
Now i don't have any email or message or my money.
The customer care is the worst part of pizza hut. i have told all of my friends and relatives not to order any pizza from pizza hut. this is the worst experience till date.
