The Professional Couriers — delivery of the courier

I booked the consignment from bangalore banaswadi office on 2nd january, which needs to be delivered in bangalore itself. At the time of booking, they promised that the consignment will be delivered by the 3rd of january. It was an application form whose last date was 4th jan-2020. So based on their promise i booked the consignment. On 4th january. I checked the status it was showing in transit. When i tried to contact the customer care at bangalore head office and banaswadi office. Mobile numbers given on their website were switched off and landline number no one responding. After trying for 1 hours. Banaswadi's office picked up the phone and said simply load was not connected and will deliver on 6th jan. Due to their irresponsible behavior applicant couldn't apply his application
