Trackon Couriers — much delay in the delivering the courier

Address:

Electronic city, 560100

Sent a courier on 16-mar-2020. Courier person said it will be delivered at max by 2 days so opted it. It's almost 3 days now, i called them to tell that courier not delivered and to ask when they are delivering it. Executive was rude and said there is no service available and they will send weekly once only to the area (It hub and sez zone). This is ridiculous and very prompt way of cheating customers.
Please take strict action on this trackon couriers.
