Good Afternoon AnthonyWatson: I interested in your business of mailroom employment partime 21hrs 3 days and available on weekends contact number is 857-237-4716 call back thank you kindly.


I placed a redelivery for my amazon package, I thought everything was going fine until about a week later, I never got my package and I am still very disappointed because I have emailed them and they say it will come very very soon but it never does. Idk just my experience maybe yours is different, thank you.


Sent some mail from here, priority and trackable. Man making label put wrong ZIP now I cant get this package to the recipient, they wont let me take it back, will not guarantee a refund. Reviewing the activity they are not even trying to send it or fix the address. They have done absolutely nothing and state explicitly that probably will not change. Basically I get "Maybe we'll send it back to you and we can try again" It's hard for me to imagine a more useless disgusting ensemble of slobs than this facility.
