Delhivery / Ssn Logistics — Package delivery delay

I have send the package on 20-may-2020 and i have paid 90 rupees for the delivery charges.

On 27-may-2020 parcel is out for delivery, then the courier boy put the status in "reschedule" without any further notification to me. I don't know why parcel is not delivered at 27th may.

Then i call to the customer support "[protected]" on 30th may, the executive says, "i have re-scheduled the parcel and will be delivered on 1-jun-2020".

Still today itself, the parcel not delivered. I m trying to customer support call for more than 15 mins, no one pickup my call.

This delhivery logistics not doing delivery on-time. Very poor. No customer support and also no email support.

Please take legal action of the above problem as soon as possible.
