Did not answer they called my cell as well left no message

They called my cell phone. I answered and it was automated telling me her name was Allison calling from the warranty center and said my warranty was about to expire. Did I want to here more about renewing my warranty, I said no. There was silence and they hung up. Allison didn't say what the name of the warranty center was.

I would like to stop getting calls from this #. I don't know who they are.
