Kingdom Hall of Jehovah's Witnesses, Media PA

These shady people keep sending letters to my home in Collingdale addressed to different people who have never lived here nor is associated with my residence or family. I send the letters back only for them to end up in my mailbox again. I called the Philadelphia Kingdom Hall and asked them to remove my address from their mailing list but it seems they only shuffled it to the Media, PA location for another name, J Romero. I telephoned the Media number listed but no one ever answers and there isn't a voicemail either (the service is Verizon). If I receive another bogus letter from any Kingdom Hall I am contacting an attorney. I don't know where they are receiving their information or how my address ended up on their mailing list but I have had enough.
