Issues with using headset in game, as well as problems creating squads.

If I turn off VoIP then I can't hear the other members of my squad, and sometimes I want to mute just one member of th squad because they are yelling into the headset, there is a toggle mute option but it doesn't seem to work for anyone. Also I have tried to quit the game and come back in but I still can't create a private squad, is there a way I can uninstall all associated files to battlefield and then reinstall? Maybe a file isnt working right

There is a toggle mute function under the squad section, but it doesn't seem to work, is there a way I can uninstall all the bf3 files from my playstation and reinstall them? Or does the toggle mute feature not work at all? I should be able to mute just one player not the whole squad or team. Also I seem to be picking up other peoples headsets that are not in my squad, I don't want to turn the VoIP function off, just want to be able to mute a player and not pick up other headsets. I'm using a playstation Bluetooth headset, if that helps any.
