You are right.
A theory that does not agree with experimentation cannot be correct.
And a theory that doesn't even agree with the theoretical principles it 
states, much less.
The SR teaches a contraction of distances (while Poincaré teaches an 
expansion of distances if we understand it well), and does not know how to 
explain the Langevin paradox in apparent speeds.
It therefore has no chance of being true in its entirety. It is only 
partially true, and essentially for the Galilean movements. Everything 
else quickly becomes false.
Experience will only be able to show this when we can test things more 
complex than those we test today (time dilation, aberration in the 
position of the stars, etc.)
