Sears trying to sell insurance

I got a call from this number today two times. First time, noboby's talking. second time a girl ask for me but it was 9pm and my husband just say that it was'nt an hour to call. What they want?

Called every day, never leave a message. Finally caught a person, say they are from Sears.

this number just called me 1:54pm, selling insurance, i just said "thank you anyway"

this number called 5 times in under 2 hours. and many times previous days.  NOT AMUSED ANYMORE!

I also get calls from that number almost everyday without being able to talk to anyone. What do they want ? Is there a way to make them STOP THIS ?
