Pizza Hut India — cheating

Address:

Ahmedabad, Gujarat

I have orderedपि ppizza online and got the order details & confirmation on my registered email ID.
Clearly mentioned in that mail that delivery with in 30 minutes after that free delivery.
Then also I spoke to Mr punit & Mr Prashant at pizza hut call center for late delivery and they have allowed me to get ₹ 300 on my order to accept the delivery boy.
But Mr Alpesh, the store manager has denied to allow the free delivery and₹ 300 discount as per confirmation by pizza hut call center.
This is very bad on no any options to serve to our guests on this time and I have paid and by force I have to accept the order from Pizza Hut.
I have order confirmation email and call records of Pizza hut call center and pizza Hut Stores number.

Please this is not fair to on confirmation and commitment by this multinational company in our India.
Because of there is no unity and association for single consumers.

This is my humble request to take care on my complaint.
