I am having problems locating a pension plan I have through Mercy Medical Center in Durango, CO.   I have a 401K also , but the pension was not rolled over into that account.   The people with the Mercy pension plan have all info that I rolled this over to somewhere else in 2014.   They also said I took a $15,0000 dividend in 2014.   They have all info EXCEPT where this $$ was rolled over to.   I have a feeling it has been stolen.   Its been a week and still under investigation.    We cant get anywhere with them .   I tried to contact the IRS and I cant speak to a human being.   The automated service could not help me.   Help !!
