Important Information about Robocalls

The HTC service area is currently experiencing increasing numbers of scam robocalls. These automated calls may appear to come from local phone numbers, but they are not local callers. These callers are illegally spoofing the originating number to appear as a local caller. These calls are an attempt to gather your personal information in order to run scams.
