Nissan broke my Engine Mount and claimed it was the fan belt

Took my car for a major service at NTT Nissan Newcastle on 20 July 2021. I was told since it's 90 000km they need to take out the engine and change the timing belt as well. Total cost came to about R7000. Two days later, my car started making a funny noise. I went back to Nissan and was told it's the fan belt that needs to be changed. They referred me to supaQuick for that. Where I was told it's actually the engine mount that is broken, and thus the engine has shifted. Had to fork out another R2500 to have a new engine mount put in.
