I keep getting calls from this number - which hangs up before I can answer.  Called back a couple of times and got a very rude lady.  She said that she did not call.  In fact her phone was on the table unused.  I told her that someone is using her phone number and that she needs to notiy her phone provider.  She just blew me off - very rudely.  I was just trying to help her because I am sure I am not the only one receiving these calls.  Obviously some scammer is using it.
