Very bad gaming experience in H2H matches

Why is it that in H2H matches, our opponents are always faster and stronger than me? Despite their low ratings. And the biggest thing is that even if I get fouled, I'm not given a free kick, the referee keeps playing, and if there's even one touch on the opposing player, the referee gives a foul. Why?? And my players' shots are very underpowered. Even though they've upgraded to level 27.
