i had the smae problem with prodigy networks it took me about 3 weeks to talk to some one and i was calling them up to 10 times a day. i eventually did get a mac code and managed to transfer my isp to sky.however i am still recieving emails from prodigy saying that i owe them money,...they still think that i am with them.
i would not recomend this company to anyone. good luck with getting your mac code keep calling them and the one guy that works there will one day answer the phone!!!
