I didn't recognize the number so I didn't answer the call.  They didn't leave a message.

calls often, leaves no message, I hear a ton of noise in the back ground.

Keep calling. Can't call back.

The first time they called the caller asked for a specific person. When told wrong number, the caller asked if this is home owner. The caller was informed no, wrong number. Since that call this number has called 2 more times and I don't answer it and no message left ( p.s. I rent an apartment, its not a home!)

This phone number calls my business 3 times a day every day.  No one answers and they hang up.  When you call back, it is busy.  I have registered a complaint with this phone number to the FTC.
