[Q] Bugs in htc sense rom for micromax canvas a120 topic

I recently rooted my phone. I wanted to install a custom rom. My friend installed cleankat v2.6 but i wanted to go for something better. As expected none of the nicer ones like cyanogenmod or paranoid android or aokp roms were available. I managed to install htc sense rom . it is working but has lots of bugs. As soon as i make a call it crashes and screen goes blank. Nothing opens .it doesnt even swit h off and i have to remove the battery every time i make a call and reboot it.
Secondly many apps including settings crash for no reason.
Plz. Help coz i really want dat rom working fine
