Can confirm. Have been one of the victims. Yes, EPCPLC indeed sends all papers after the deadline has run out with an alleged sending date weeks ago, always illegaly from continental post offices that don't stamp dates on the envelopes. I've contacted those post offices and inquired their normal run times to be in the one to three days period, and not six weeks like the alleged dates would suggest.
When I googled them for the first time, their homepage was in the middle of the first result page. All the other results were fraud warnings. Respectable and established websites had articles on them recommending involving a lawyer before contacting them, as the company was "known to be not trustworthy", a position that I can support to 100%.
I am still thinking of file a fraud case against them, and of there is a call for witnesses against them, I surely will support the agency that is doing the case against these fraudsters.
