I had IRA (former 401K) accounts at TRP in 2008. To correct some very small errors, they transferred 100% out of my accounts and on long New Year's weekend only transferred back 2/3- so that 1/3 of my shares were missing. Then the guy performing this went home for 5 days.
They did not tell me they were doing this and employee left no notes in computer. When I called about missing shares, TR Price employees could not explain to me for 5 days, when employee returned to office. They claimed they did nothing wrong. I got all my retirement accounts out of TR Price as fast as I could- never to return.
