This number calls three or four times a day.  The caller ID says it's a local number and it shows "Dettmer Warren", whoever that is.  I've blocked it so I have never spoken to the individual, but even blocked, the constant calls are annoying.

This number is a March of Dimes solicitation call center.  Calls frequently, but never leaves a message.  I called back and got a recorded message identified as the March Of Dimes.

It is a call or returned call within the call center network under the fundraiser / solicitor / telemarketer / membership services of Infocision Inc. see https://www.sos.wa.gov/charities/search_detail.aspx?charity_id=2835 that lists the legal alternate names used under March of Dimes and lists the fundraiser Infocision Inc. see https://www.sos.wa.gov/charities/search_detail_cfr.aspx?cfr_id=66 325 Springside Dr
AKRON OH 44333  Phone (330)668-1400. It is well within your consumer rights to file a complaint and demand for placement on their internal do not call lists to stop the calls.
