Scam or fraud: On-Dot Couriers & Cargo — very poor service(no delivery of courier in time and also not informing about the arrival of courier)

Actually the courier was sent from Chandigarh to dehradun through on-dot courier service.The courier was sent on 4th of august 2018 but it was not delivered up to 9th of august.so, I track down the courier through the consignment number.Then i got to know the package or courier was delivered to dehradun on-dot courier service branch.When i called to the dehradun branch office.The official who works there didn’t knew about the courier.She wasn’t so responsive and was yawning while talking.I had the emergency.so i went to collect my courier.Actually i had two courier sent from Chandigarh with different time or dates.But both courier were not delivered. Worst service ever.
