Swiggy — denied delivery after taking full payment

Delivery person denied delivery as he has some personal issues in the locality. Top of that they deducted charges from my payment for Their own faults. Even after several telephonic request Swiggy denied delivery of food to a lady, and they say they dont care, we may complaint to any authorities.
After full payment food denied to a lady was waiting for her food to deliver, but Swiggy and the delivery person denied delivery after full payment as the delivery person has his personal problem in that locality..!
Totally unacceptable
