Mcdonald's India — Order is late after payment was done more then 1 hour ago

I had placed my order on mcdelivery at around 11.30 and it is now(at the time writting the complaint) 12.40 and I have yet to receive the order and I have tried calling 66000666 ... But the no. Is not valid was being told, and I tried customer help line[protected] but no one is picking up the phone after going through all the process.

I tried calling the no. Provided in mcdelivery +[protected] but it says no. Is switched off ...

To whom should I contact ...
Very pathetic after sale service of McDonald's

Never expected from them.
