This is a comment forum, they can't block anyone. You need to get a call block device. Some are available locally, or at Amazon.

After a silent pause, heard voices in the background. A female caller asked if I spoke Spanish. (I do, but declined to answer yes) She then hung up.

Called, I did not answer, they did not leave a message. BLOCKED.

Pick the phone, they are scam artist, tried to say we owed money, I told them that they need to speak with my lawyer, after I cursed them out!

Called and immediately started speaking Spanish. When I said I didn't speak Spanish, she said she needed to speak to someone who could. Hung up.
