Q. I bought 100 shares of PSE&G in 1979 for $17 a share. Through the years I had dividend reinvestments. In 1982 I transferred the shares to some brokerage house, which was bought by another company in 2015. I sold 500 shares, but now the brokerage can’t get me a cost basis, saying they didn’t have the shares long enough. I gave them all my info and they can’t do their job. What do I do?
