l recently got a 1996 cinquecento s and within two months the handbrake cables snapped. Since getting the problem fixed the handbrake has been even looser than normal, and l cannot use the handbrake on hills as it would roll back...is there anything that can be done about this? and will it cost a lot?

Get the cable tightened.

this is not a big problem at all. just take your fiat to a fiat mechanic and they will tighten the handbrake cable. probably u like using the hand brake!!

Adjust the break cable you might can do this very easy get your tools out and tighten up a little not a lot its a new cable and may have to much slack in it , hope this helps.
