Delhivery — Shipments not being delivered

Address: Nellore

Hi
All the shipments to my address are not being delivered. They are not even contacting me and returned the products after keeping with them for few days. The worst thing is that they didn't even have a customer care number to contact. In mails they will just reply that sorry for inconvenience, your product will be delivered soon. After few days they will just update your product is returned due to operational issue. Seems like they have operational issues 365 days in a year.. suggest to close business in this area so that some other will do that.
Below example shipments
