The service of this Courier company is not at all professional. While delivering a courier if the door is locked, there should be a slip left to call back or the customer should be intimated that the courier is with them. More often the customer comes to know of the courier only when it is returned to the sender.
Intimation should be made mandatory, as the documents that they are delaing with are very important like Cheque books and the like.
An appeal to ICICI to stop alliance with this courierr service for cheque book deliveries.
