Zomato — banjos food

The delivery guy just called me once and i called him back within 1mins a d then called him 3 times and the restaurant too none of them answered.
And the order was cancelled within few mins with no refund this is not acceptable at all as i was the one following up endlessly and they just did a favour of calling me once.

I spoke to the zomato help desk but they are least bothered just doing the formality.
It's not the matter of money it's the matter of consumer service and should be strict from the government and act on this firms which take things lightly as most people do not even complaint
