ip-p2psupport.net is, I'm afraid, certainly nothing to do with Limewire.
If I ever make an online payment, I always record the url where I made it and the transaction deteils. It is possible to get hijacked from the official limewire site by spyware on your computer , and possibly by cookies of a harmful nature.
You may be a ble to check what site you ended up at through your browser history ... depending how far it keeps records.
Limewire cannot be reached by telephone and any site that says they can be reached by phone, is most certainly a scam site.
As I have said ip-p2psupport.net had sold you a non existant membership to Limewire.
Limewire can only safely be obtained from
