Madhur Courier — Madhur courier complaint

Hi,

I had sent my copies of exam from Tikamgarh to Bhopal. Copies were received on 16th July 2021 at Bhopal main office of madhur courier. Last day of to submit copies was 20th July 2021. From 16 I had take followups from main branch and request them to deliver before 20th July, They assured that they will deliver on time. But they didn't do what they said. As also they don't have any contact point . While talking to their customer care number their executive are cutting the calls without providing full details.
This is so ir-resposibile behaviour. Kindly take a strict action on these type of firm.
