Mcdonald's India — Errors in the bill

Address:

Hyderabad, Andhra Pradesh

On 19th may 2015, i visited McDonalds @shaikpet branch, Hyderabad. I am surprised to see the bill of this world reputed brand. The cost of individual items doesn't sum up to the total that mentioned below. Have a glance of the bill below and take your stand on sharing it. I tried contacting them through email and facebook but then dint respond properly. We can check and ask for refund but what happen to service tax that need to be paid to government. I cant know whats going on utill some one from the comapny respond and give the explanation. I doubt Online server cant do this blunders unless did voluntarily
