mac

seems my isp(prodigynet) has disappeared from the face of the earth.
Been with them for about 4 years on adsl and all was alright until about 6
months ago.
Then my ping and connection started having problems and to resolve the
matter I tried to get in touch with them.
I emailed them quite a few times, phoned them, still no response.
All I needed to know was if it was their problem or BT's.
I decided to move on to another provider.
I have asked for my MAC by email and recorded delivery letter, but still no
joy.
No one answers the support phone or the sales phone.
If they are going out of business well ok but at least let us punters know.
Could it be that this is a way to prevent me getting my MAC.
Its all in the hands of OFCOM now, so if anyone hears anything about
Prodigynet please post here.
