Paytm Mobile Solutions — order delivery marked delivered without delivering the product

Address:

Pune, Maharashtra, 411021

Hi,

I want to know why my order status is 'delivered' when the product is not delivered yet?
Atleast the courier should call and let me know that order will be delivered late or whatever before marking the status delivered.
The paytm mall app doesn't have option to raise a complaint.
The order delivery section says please call the courier.
The courier is not responding.
The delivery guy never called me where he delivered the product.
The paytm customer care is not responding.
The order was marked delivered purposely after 6pm so that the customer care service is not reachable.
The machine says their working hours are 10 to 6pm.
Now its a weekend and the app says such issues should be raised within 72 hours.
What kind of service is this?
Please respond.

Thank you,
Prasad patil
