I reported one of their customers some time ago, and after receiving absolutely no response, decided to try other methods of contacting them - both via telephone and MSN, neither resulted in my being able to get in touch with them.
Because of this, I went above their heads, and got in touch with their upstream provider, Above.net. They sent the following to their customer;
This resulted in my receiving a CC of APS/3FN's reply to Above.net;
Where [REMOVED] is my e-mail address.
Sergey's response however, is absolute rubbish as I DID send them reports of abuse, and have copies of the reports I sent them. More interestingly, Sergey also seems to have completely ignored the other sites I reported, instead opting to mention only two of them.
Annoyed with Sergey's response, I sent him the following reply (CC'd to above.net);
And what did Sergey have to say about this? Well, absolutely nothing it seems, as I've received no further response. I've re-sent this a few mins ago.
I've just got off the phone with Above.net a few minutes ago as I've severely lost patience with APS/3FN, and they've advised me that their abuse dept will give me a call back. I'll let you know what transpires.
Needless to say, just like regtime.net, APS Telecom/3FN, seem to be more interested in the money they are making from their customers, than dealing with abuse.
