I might be able to help you here matey, when I get home I'll email you the fitting instructions which tells you how to adjust it to get the shut lines right. Hopefully that'll help/assist.
As for the attitude, I'd email Graeme at Zeintec S.A - the boss!. He's be superb with my order/questions and has been really helpful. As I understand it Zeintec USA are only an authorised distributor and the Zeintec themselves are based in South Africa - I'm sure Graeme will be none to pleased to here of bad /lack of service you've had, hell you may even get a freebie!
Dont want to post his email address here, but I can PM you if you like?
