Who called from 8603517559

This is a phone call from Plainville Connecticut.  They called my phone on three different occasions using three different phone numbers, 860-351-7530, 860-351-7559, 860-351-7693.  I don't know anyone in Plainville CT so I didn't answer any of them.  Using three different phone numbers tells me it has got to be a scam.

Unknown number sick of them

I got a call from this number too, and another 86 (0) 351-7553 but it's labeled as Taiyan, Shanxi, China.  Spam.  Block.

Dont know who they are

They just call and hang up...they don't leave a message.
