Can't seem to get my number ported

I moved from one neighborhood to another in San Francisco. I used to use RCN for cable, internet and phone. In moving, I moved out of their service area and am now a Comcast customer. I can't seem to get my number ported as Comcast and RCN disagree with what is needed to port numbers. RCN says that Comcast has to pass my OLD address (for which they have no record) in the LNP for verification. Comcast says that there is no need to pass that information (for which they have no record). It has been almost a month and I spend over an hour a day on this. I am REALLY furious and will be filing a formal complaint with the FCC. Anyone have any other ideas?
