Delhivery — Collection not done, no proper update, no refund policy

Address:

Plot 5, Sector 44, Gurugram, Haryana - 122002

I had placed an order for pick up and delivery of a shipment on delhivery, it was supposed to be collected 2 days ago but that didnt happen, when i track the status on their website, there it is mentioned shipper unavailable when in fact their delivery executive never went to the location for collection. they dont have any customer care number mentioned on their website. i want to refund my paid amount but there is no option available on their site.
highly unprofessional and unethical behavior
