EAD never delivered

[lala1 21]

So my EAD appears to be lost in the mail somewhere..It says delivered on their website but there was nothing in the mail box when I checked.. I've searched this website for similar cases and it seems to be a common thing with USPS losing important pieces of Federal mail .. really ? How can they be so careless ? I've seen several threads of people complaining about them losing their green cards and or EAD's and tell them they claim no responsibility for the loss. How can someone pay almost $2000 in fees only to have their cards end up being lost in the mail somewhere or handled by an unreliable postal system? Ridiculous.. I've opened an 'inquiry' with USPS and they said that will take them 1 business day, and I spoke to a supervisor over the phone from USCIS and they are seriously telling me that I have to refile and pay a fee of $380 even though I've already paid $1490 in fees and have a pending AOS, They claim no responsibility.. absolutely ridiculous... This is not the first time I've been in this situation with the USPS..The last time I rose hell at the post office until they found my package, definitely gonna have to make my way over there.. SMH
