When the parcel reaches the destination, don’t sign the delivery confirmation without hesitation. If you sign for the item in 'good condition', you will not be able to process a claim. Instead, check its condition in the presence of the courier driver. In case the parcel arrives damaged, ask the courier driver to file a damage report.
Without a damage report, the claim is likely to be rejected by the courier company.
Please note that allegations that the courier driver left too fast or that the damage was discovered only after opening the parcel, will not be taken into consideration by the courier company.
