Hi Kath
Had the same problem with mine when I bought it, There is a simple adjustment you can do yourself, Inside of the center console between the front seats ,remove the bottom cover, it just lifts out and you will see the handbrake cable with the adjustment nut, with a correct size spanner think its a 10 or 12 mm turn the adjusting nut a few turns to tighten the brake cable as advised in your Hand Book and this should solve your problem.
