Nsdl E-Governance Infrastructure — PAN card not received even after 21 days of being dispatched

My PAN was dispatched by NSDL on December 28 2021 by Trackon Couriers, courier vide airway bill no.[protected]. PAN cards are received with 7 days of being dispatched, but I have not gotten it even on the 19th day ie. January 16, 2022. I urgently need the physical PAN card. Not to mention the consignment has been in the distination city from January 1, 2022, but it has not been delivered and is still in the warehouse. There has been no contact to me by the company regarding such a delay and none of the numbers provided on the website work. I have personally called the contact person Mr Dinanath ([protected]) DOZENS of times but the dial tone is always busy and he has not once called me back in so long. This is irresponsible and being such an important document they should be careful and respect the time of the customer. I have also sent a complaint regarding this on 16 January 2022 but no response from Trackon. Kindly help at earliest possible.
