Got calls from this number but the first one ended with xx39 from IL, USA.  I don't answer calls from unknown numbers and the first time they didn't leave a message.  Second call from number ending xx36 (also IL, USA) left a message from Best Buy to confirm delivery of a recently purchased appliance.  I wonder why a legitimate business doesn't clearly identify themselves on these types of calls or call from their business number showing up on my paperwork.
