Received a call from this number. It rang two times and they hung up. No message left. Coincidentally, this call was preceded (by 4 minutes) by a call from 713-874-9998. Exact same situation; rang twice and hung up, no message. I think they are related.
Received a call form this number and when I picked up a recording said:
"Call from _____________. To accept, press 1. To leave a message, press 2."
I opted to hang up. The "____" that I put is not to protect the identity of the person whose name was mentioned in the recording. There was no name mentioned, only silence. Um, okay. BLOCK.
they called and hung up, no message. I called back from the landline and it said "no loud sound" repeated it several times with intervals of quietness.B
