Who called from 8563422000

Received repeated phone calls from this number, 6 to be exact. Then a suspiscious text message from 856-342-3211 in an hour span.

Tried to sound really creepy but I was lmao.  kept saying things in a hushed voice so I just stayed on the line, thinking it was a prank.

This is Cooper Hospitals Main number

I just had a CT-Urogram done at their Voorhees location, so it very well could have been Cooper Hospital.

I THINK the caller asked for my husband -- but there was so much amplified feedback in the telephone line (like a voice-disguiser) that I said: "I can't hear you well, there's so much noise in the line" and the caller mumbled something about calling back.

Cooper?
