Bad service Suzuki Centurion

<p>Booked our Suzuki for a service at the Suzuki Centurion branch, also to have a "airbag light" checked out, which remains ON. To cut a long story short, they were unable to fix the problem and apparently the battery is faulty, which by the way is 6 weeks old and tested 100%. They then advised that a larger battery must be fitted, only problem is that the the terminals must also be changed as they do not fit on the larger battery.After sales/service manager and manager VERY unhelpfull with" not their problem" attitude. Problem still not resolved....</p>
