Came home from vacation to find many calls from this number on my phone log. ID - Research Center. After ignoring a couple of calls I answered, listened briefly to the spiel and told them I wasn't interested in their survey and to take my number off their list. Within 2 hours got a different person from the same number and told them to stop calling or I'd file a complaint. Next call my wife answered and repeated our intention to file a complaint. Next day, after two more calls I filed a complaint with the FCC and emailed the company with instructions to take our numbers off their list (they have been calling 2 of the three land lines in the house - alternating). WIthin 3 hours of the last call / complaint / email got another call. These people are relentless and do not care about the law.`
