Keeps calling

I have numerous calls in the last month from this number with a recording saying is this so and so.  Finally I am aloud to touch 3 to say it is not but they still keep calling.  They are looking for a person by the name of Karen ....  Thats not me.  I assume that this person had the phone number before me and the place that is calling has this number as well thinking that the same person has this number.    One would think after so many calls to the same number and no reply that they might think that the person that they are searching for has moved  and no longer has this number. Duh!

I have had many calls from this number last 2 weeks and no message left ....no pattern to the times the number shows up either.

Any ideas?

I keep getting calls from this number and no message is left - its going on 2 weeks now at 2 times a day!

A computer noted that the call was for Daniel Mixelin.  I redialed the Caller I D and the call was answered with the question "Is this Daniel Mixelin?".  When I inquired who was calling - they hung up.  I would like to stop this as it happens quite often.
Anybody have any ideas ??????????
