thanks to all who responded. This "425" number has been driving me crazy with calls every day (which I haven't been answering). Yes: I was in Kmart and was dumb enough to give Penguin my cell number due to some contest they were having. At least I know now who it is bothering me.
I gave my cell number to a company who sells windows and another who sells heat pumps/furnaces. My guess (425)245-0321 belongs to one of them. When I get a call back and answer, speaking to them, I'll find out the name of the company and post here.
I received a call from this number and finally answered it - it was Penguin Windows. I filled out a form at a county fair for a free window. I asked them to remove my name and number from their list, and I did not receive calls from the 425-245-0321 number again. However they started using other numbers, such as 425-608-7755, to continue to solicit my business.
