These calls are driving me crazy. I've recorded a minimum of 3 calls per day for the past month. I am going to try a few of the suggestions from the previous postings. Maybe proactively calling both charities will also help!
I am having the same issue. I blocked their number (901-248-0600) from call me. I use Comcast for local phone service and their feature code is *60. If you use Comcast, the next time you receive a call from this number, hand up, get a new dial tone and enter *60 and a Comcast recording will confirm the last number that called you will be blocked. Then Comcast will speak the number 901-248-0600. This way you will know the the number wanted blocked is the right number.
For all those who use a different local phone service provider, I'm very sure they have the same capapbility.
We too get at least two to three calls a night from this number, 902-248-0600. Finally called with the cell phone and got a voice mail saying it was Kimberly Kennedy, but then was disconnected. Have now blocked the call. Will see if that helps.
I am also getting these calls several times a week. They leave a voice message each time of several seconds of silence. We have answered a few times and them does not seem to be anyone there.
