I try to answer you also if you didn't wrote a clearly question .
Anyway airlines companies could change your airplane type , or can re-protect you without inform you ,the most important thing is that the carrier have to guarantee you a same departure and arrival time and same class of the ticket that you booked .
That is about a general rule for all kind of travel services . For instance you can book a four star hotel , when you arrive to the hotel the hotel it's fully booked and it will ove you in an other hotel with similar feature ( in this case you cannot ask a refund ) .
Regarding some changes about seats reservation or airplane type , I think that your travel agent miss to read the message queue about changes in his GDS ( ex. Amadeus or Sabre ) . If he is an Iata Agent and then he have a GDS system , I suppose that he didn't see this message , that we usually receive .
Have you got a fare basis just to check the fare rules ?

It's unlikely there is anything you can do about this, other than booking a different flight.
Changes to bookings happen all the time. Many are more serious than this, such as changes of departure day or even destination. In almost all cases the limit of the airline's liability is to offer you a full refund. I would have expected them to inform you, and you might have some cause for complaint there.
You really have only two options:
