They called me twice while I was on another call for 26 mins, but left no message. Since I do not recognize the number I will put them on my Do Not Answer list.
I called a Chicago number for business purposes and within 5 minutes got a marketing call from this number. Its now clear to me that the marketing companies can now profile and track our outgoing calls and then call back from an area code in the same area or city. I am sure there is some type of research that shows if you call a number you are highly likely to answer a call from the same number. I thought it was a return call from my business contact.
