Food Panda — food not delivered but amount deducted

Address: 110075

I order food through food panda app from la kababiya restaurant, dwarka sector 7 and did not received any order but my payment was deducted from my account as i paid online.

Delivery boy (Vikash yadav - [protected]) didn't pick up phone calls.
Vendor la kababiya said its not under his scope
No valid complaint number of food panda available.

What should i do in this case?
As it is happning thrice with me.
