Who called from 9518467204

Same here

I got 2 calls. When I called back it went to a system saying my call was important to them and to wait on the line.. Just hung up. Not sure who this is.

2 calls today. Did not answer. No VM left. Called back to a recording without company's name. Added to reject list.

Same here

Two calls yesterday, another today so far.  Doesn't leave message.  Getting annoying!
