I advise you to invest a little in a course of good manners of your employees, as well as understanding the written Italian: after paying the extra for delivery to the floor, the courier (a peasant of the first category) arrives and not only refuses to bring the package to the floor (later it was found that he had written it), but also refuses to give any explanation, to call the offices to clarify a possible misunderstanding, etc. In addition it is also unnerved because of my (legitimate, since I had paid) requests.
Clearly in the family we will take care to never have anything to do with you again and I hope, I repeat, that you change your selection criteria a bit.
