I recieved a  call from this number in December 2010 they are a precious metals brokerage of some kind and had purchased my number from some one claiming to be in the same industry some time before 2008. The man identified himself and our previous conversation from 2008. I was very short with him and immediatly asked him to stop selling my number to others and stop calling me. After this he would not tell me the name of his company and things quickly escalated into him telling me to f*** of and f*** you etc. I did not loose my temper. I even called back(unfortunately he had call display) and he still would not identify his name or company name. I believe that any company that sells these kinds of products should have all numbers listed and should identify themselves by my stards this is very suspicious.
