Should I be concerned about the robocall from 0421309094?
One report of a robocall from 0421309094 delivering a voicemail system message suggests automated contact rather than targeted fraud. However, robocalls can be used for various purposes including spam, scams, and unwanted marketing. If you receive the call repeatedly, treat it as a nuisance and block the number.
