Domino's — Charging extra amount on vat

Address:	Hyderabad, Andhra Pradesh, 500073
Website:	domino's

I have bought pizza at domino's on 7-may-2016. Attached the file for your reference. They are charging extra amount on vat. And they are charging service tax on 100% of the bill, but the actual thing is they should charge on 40% of the bill. As per the bill my subtotal is 649.37, on this they have charged service tax @5.8% which came around 37.41. They also charged vat @14.5% which should come around 94.25, but they charged 99.58 rupees, they charged vat on service tax too. Why are they charging double tax?? Please correct me if i am wrong, if at all they are cheating please register a complaint.
