VRad VRad job application agreement Minnesota

I retired a while ago, and VRad assured me they will  give me an opportunity to work with them doing teleradiology if I  enrolled in an accredited mini fellowship in order to bring myself up to speed.

The fellowship would require I  read a given number of  cases of various modalities -    ( type and number were pre- determined by  VRAD) and obtain  references form such  fellowship.

I paid $thousands for the training, and a few days before I  completed the fellowship, VRad called me  to  announce that they  decided not to  work with me  unless I extend my fellowship to a six month  period of time. This  changed the whole agreement we had, and I find this unethical. I  will submit this grievance with documentation  to the ACR where I am a  a board certified member.
