Purolator review: delivery service/driver

I had placed an order online (amazon) and was given a tracking number for Purolator to have said package delivered to me on Monday, Nov 25/19. I was home all day that day, as the day went on I kept checking out my window as I live in a secure apartment building with no buzzer. Later that day I decided to go check the tracking it said it was delivered at 1:18pm except it wasn't, there was no package and no slip or attempt to get in the building to leave at my door on the third floor. I had called Purolator the next day to inquire about my missing package. The lady said they needed to do a trace on the vehicle and driver, in the meantime I went to our local depot to see if maybe it ended up back there. Nope, the manager of the depot was completely arrogant and not sympathetic to the fact they lost my sons Christmas gifts (package), she told me I'd have to call and open a case file in which I had already done. Once I told the woman she got more rude and refused to help further. Told me to wait for the call, on Wednesday nov 27/19 the trace specialist was very kind and compassionate even went an extra step to contact the driver. Thursday nov 28/18 I received my last call from the trace specialist a different lady this time who was not at all nice she went on to state the driver is sticking to his story about leaving it at MY door. How can one leave a package at MY door when I live in a secure apartment building and live on the top floor. IMPOSSIBLE, they then pushed blame on amazon and told me it's their issue. She also added in that the driver made one attempt when they are to make one attempt leave a notice and try again didn't happen he simply just left them outside of my apartment building on a main road to boot! I do not and will not ever recommend Purolator for any delivery services.
