The problem is that all Filehosts, operating now, have hundreds of new members and uploaders contacting them and they maybe cant cope with all the many emails coming in, as they only have so many staff.
So if many keep repeating the same requests by sending multiple emails, the delay will be even longer before anyone receives a reply. Just be patient. I was, and eventually got replies from some.
Some explained they are working on improving many things on their sites, their affiliations, and their service in general, others didnt reply, like ul.to, extabit,and turbobit. I have warned uploaders both on my site and this one, over and over again, not to use those three if they want a fast reply service.
I also repeat what I have said before,,,,,,,the ones that offer the best paying rates are not necessarily the best ones for you guys.
