My letter or my parcel is stuck on the mailbox. Why does the sending fail?
Please check if the addressee's name is spelled correctly. A single typing error such as a superfluous letter or a blank space behind the name can be enough for the sending to fail. If it is a parcel you would like to send, make sure you placed the label in it. Also note that you need to have a parcel or a letter that has not been used before for sending mail. Mail that has already been stamped will not be delivered a second time.
