It seems they have moved on to Portland area codes now. They called my cell this morning, didn't leave a message. I am on a Pay-by-the-Day plan, so their useless ringing of my phone cost me $2. Annoying.
I frequently get a call on my cell phone from 415-363-9552 but I do not answer. I have no idea who it could be and don't want to waste my plan minutes on it.
