Who called from 8562040652

I'm up to 7 calls from this # today, at my work number. I'm no longer even bothering to pick up (I was leaving the receiver on my desk, not saying anything, till he hung up). How fun! (Sarcasm)

This number keeps calling my employer asking for people who do not work here.  They are very rude, and ask intrusive questions.  When I asked who they were calling from, he replied OSU Medical Center.  The area code is from Jersey.

someone claiming to be from Bank of America and called to verify the company phone number

call from that number,  did not answer call, no message was left.

im thinking all these numbers are linked. but please could someone tell me how to stop the calls? i black listed the number on my cell phone but now he keeps calling my job which happens to be a family which my papa owns and my papa and dad get on my [***] because they think i owe money until i keep proving to them its a scam or whatever. smh im really tired of it.
