Mcdonald's India — Vat

Address:

Hyderabad, Andhra Pradesh, 500081

Hi
I have ordered a regular McAloo Tikki meal for home delivery.
order no is : HIT[protected]
Price of item is Rs 91 only, but VAT deducted on this is Rs 18.16.
This is about 19% of the prce of the item.
As per my knowledge VAT should be 14.5%, but amount charged for me is more than 14.5%
The prices of the McDonald’s products are inclusive of Value Added Tax (VAT) but exclusive of service taxes and delivery charges.
But my bill is charged 19% VAT.
Can you please send me a authentic mail to resolve my problem.
