Delivery failed due to "Receiver not available for final delivery" but no one tried to contact me

I had a package that had an estimated arrival time of 17h00 on the 23rd of December. At 16h40, 20 minutes before the expected time, the tracking page states that the "Delivery Failed" because "Receiver not available for Final delivery." Nobody tried to contact me to see whether I was available or not, as I had no missed calls or anyone showing up at my door. Additionally, I phoned the helpdesk who told me they would be working on the 24th, however the package was unloaded on the 23rd and never loaded or dispatched on the 24th. I would avoid using this company if you need your items delivered in a timely fashion, because they do not stick to the estimated times that they provide.
