How do I unsubscribe from the robocalls???

[rjkp.livejournal.com]

 I apologize, as this is kind of the antithesis of a Davis Square-centric post, but I moved out of Somerville several months ago, and I am still getting robocalls.  I have called the City of Somerville four times now to ask to be removed from the call-list, but I am still getting the calls.  Does anyone know of a way to unsubscribe from these?  I know it's just a few extra phone calls here and there, but when winter comes, I know they'll be coming more frequently to alert me of snow emergencies, and since I don't live in Somerville anymore, I don't really need the alerts.

If anyone has a lead, let me know.  Or, Tom or Jackie, if you are reading this...help???
