Blue Dart Express — undelivered item silchar

My item was expected to be delivered on 6th dec but it didn't, and it shows in tracking online that it is incomplete address, then i called up blue dart office at silchar, they said they will delivered on 7th, they informed me that it was typing error and marked as incomplete address. Since it is an office address, usually all items are delivered on time without any hassle. Now i am worried that the item may get returned for which i have already paid online and create a trouble for me to get refund. Waybill number is [protected].
