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 ?
