Who called from 2545351804

Got a call from 254-535-1804. No voicemail left. I'm assuming it's the same people calling, but using different phone numbers every day.

Didn't answer. The call showed up on my cell as from Kenya, Africa like this: +254 53 51804,
but I'd suspect it was from Texas 254-535-1804 instead.
No voice mail was left for me either.

Received a call from this number too, 254-535-1804. Call appeared from Killeen, TX. I've been getting random calls from different numbers almost everyday. Just don't answer any of them.
