Who called from 6135914628

Received a call, no answer, but the 2nd number appearing under the caller ID is 8 526 452 1890.

Received a call , no one spoke and hung up few seconds after I answered the call.

it is an air duct cleaning service.    I tell them once a month not to call my place of business, that we have electric heat.  they don't promise to stop calling, just hang up.  If you try to call back,  you get a message from Bell saying that the number is not in service, so there is no way to complain or get off of their call list.
