False delivery notices

<p>Both my sister and I received failed delivery notices within this past week, without any attempts to deliver the parcels. </p> <p> </p> <p>I am at home 24/7 and not once was there an attempt to get into our apartment complex to deliver either parcel. My number has been provided, but no calls were made to me from a phone or from the intercom at the gate. </p> <p> </p> <p>To add to this, I receive what appears to be an inaccurate tracking updates from SAPO and other parcel trackers' websites. I checked the post box at around 16h20, and no delivery notice. But when I checked the tracking details during the evening, it said failed delivery at 15h19. Perhaps the delivery system's times are just inaccurate/flawed, and that would be okay, but this doesn't make sense. No attempted delivery and no notice after the reported time of the **** delivery attempt. </p> <p> </p> <p>Could someone explain to me why what's going on here? Could this be corrected please? </p>
