Architects retain copyright but once drawings are paid for / released you have a license to use them for the purposes intended i.e to build the scheme - and this can be with a new architect once planning is approved. Stage 4 drawings add so much detail that usually the planning (stage 3) drawings are effectively only a guide anyway.
But assuming you can restore communication it's might be more efficient/cheaper to get the in-progress stage 4 work revised rather than the hassle of terminating the appointment. I can't see why they wouldn't - especially if they have potential of additional fee payments at stake. There must be some explantation for why the drawings don't show what you discussed.
