Delhivery — Non compliant Non responsive

This company is secretive about providing contact numbers for their customer service. Emails are either responded with a "we apologize for your frustration" or not responded to at all.
Delivery dates aren't met. Tracking system is bogus and deceptive false information is posted instead of factual. Packages lying at final destination for 4 days remain undelivered and every day the "estimated delivery" changes.
