Block unknown Spanish‑language calls before they reach your inbox. If a voicemail arrives in a language you don’t speak, treat it as suspicious and avoid returning the call. Let your carrier filter foreign‑language spam, and consider adding the number to your phone’s block list. Never share personal or financial details with unfamiliar callers, especially if they claim to be a debt collector or loan agency. Verify any alleged debt through official channels, not via the caller’s request. Report persistent spam or harassing calls to the FCC or your local consumer‑protection office. Keep a record of the number and any messages for future reference.
Without understanding the language, it's impossible to confirm whether this is a debt collector or not, especially given the 'Unable to understand' comment.
A voice mail in Spanish was left on my phone, but I've had this number for over a decade and don't speak the language, so I won't be returning the call
