Delhivery — Consignment Not delivered

Our Consignments have not been delivered for a month and the delhivery team provides incorrect remarks regarding the current status.They have even mentioned that they cannot locate the consignment the day after the delivery transporter says that he has loaded the consignment in his truck for delivery.We have even taken the sales executive on con call with a customer as they mentioned that the customer was unreachable and gave him the customers number again on call, but despite that the next day we were sent a remark that they do not have contact details and that customer is unreachable.
They have no customer service contact number to raise a ticket.
