Who called from 7242096600

In the last 2 months alone, I have received at least 10 calls from this number.
The interesting thing is that it's hard to block, even thought the number comes up on my call records.
I usually do not answer it if it comes from this #

Call for me from "Omega Services" still on my caller-id on my house phone. No idea who they are I tried looking them up on google but its like a plastics company in England and I live in the US. Also its a job training place? I dunno couldnt find much about it.

I keep getting Omega Services calling me 3, 4, 5, times a day and no one answers when I pick up.

Calls weekday mornings at 9:30 a.m. EST, rings three times then disconnects. Disconnects immediately if I pick up.

This number has kept calling my cell phone and when I call this number back to ask whta they needed, they ask for detailed information about my phone number and zip code.
