I'm from Malaysia and I have a maxi cosi opal. Bought it sometime in September 2012. However the seat belt harness is now stuck - suddenly stopped from being able to be extended. It can't be adjusted at all. It's so frustrating. We can't seem to be able to make the belt any looser. Baby boy happily climbing out of it when the car stops moving. Hope you can assist my problem. Thanks in advanced!
