Tired of receiving unsolicited calls

<p>I have been receiving calls from outsurance from ********** 880, they say that my number was provided to them from a family memeber who is happy with thier service. I asked this family member and she said she would never give my phone number out.</p> <p> </p> <p>I received 15 calls from them yesterday that left voicemails on my phone, blocking up my voicemailbox, all with just random voices in the background, no message at all.</p> <p> </p> <p>On top of all of this I have been on teh DMA for the last 7 years and do not wish to receive such calls. I would like to know where my details were legally obtained from as the explanation above is just not good enough and also why I am being called if I am on the DMA.</p>
