I received a paper with a certain tracking number that said it was too be delivered but it was not (the paper said it was undelivered the day before it was marked for delivery) Then on the website, it is showing this same tracking number won't be here till a later date. I'm not sure what's going on but if packages are to be delivered on a certain date, I think it should be there in that date. Then another person got a package that wasn't even on the informed delivery website. It's very unnerving to say the least.


Lazy Lazy Lazy . Get out of your jeep and do your job stop messing with my deliveries.
