Call saying it was a courtesy call to inform me that my auto warranty has expired. This is a scam call trying to get you to say certain words so they can charge something to your phone bill and have a record of you saying okay or yes. Something similar!
I saw this odd number. I googled it, while it was ringing, I saw the statements here. I decided to answer the call. The line was silent for 11 seconds and then disconnected.
