I had 2 calls from this number today. The caller ID listing was SVC 425-406-9528. I answered the 2nd call it was a recorded message that stated don't hang up this is not a sale call. So I hung up. This SVC has been calling on and off for the past month.
SVC has called several times, but from a different Washington State number. I don't answer callers I don't recognize.
SVC uses a CallerID4U landline. CallerID4U is a phone service provider that hosts all the scams calling from the Pacific Northwest.
