Update:
My Globelines broadband connection can, for some time now, connect me to Philmusic without difficulty, and without the use of proxies.
I used to have the same access problems as you guys (always getting directed to Sedoparking, even if using different computers or my phone). I constantly bugged them for more than a month (professionally, I hope), and they even sent a tech guy to visit my home several times to check my computer, change my modem, etc.
However, they fixed my problem by doing something in my area's switch. They sent a lineman (not a tech guy) to repair a switch (or something) that controls my area (i.e., outside of my house, somewhere far). Turns out to be an infrastructure problem.
FWIW, this solution might also solve your problem. Sorry for not suggesting this sooner.
