Plums, I believe that if you only send average tunes unlocked then you are doing yourself a grave injustice. After all, your basic tune as you call it is just as much a hacked GM tune as is your all singing all dancing tune.
I think it has been said before, what makes clients return is SERVICE which includes what happens and how fast it happens when a problem is encountered.
Despite all the debate the real problem here is that Box was NOT advised the tune would be locked. I would hope that had box purchased one of your tunes that you would anticipated that he, being in central Oz, and having already advised he would have the car dyno tuned, would require an unlocked tune.
As to the question by Sideshow " but what is the law regarding bad mouthing a business on public forums?"
Have a look here:
http://www.recalls.gov.au/view_recal...ecall_type=all
That's a list of products recalled from the market in the last 30 days. Behind every one of those recalls is a sad tale to be told by a consumer. Sure, some recalls are because the manufacturer/vendor identified a problem after distribution but in most cases the faults originated in the public forum.
Now...keep in mind that these are only recalls which pose a threat to the public. It does not include the recall of products which pose no threat to health or safely.
If you will have a look at product 2008/10341 on that list. It is for the front hub assy. of a commodore. Here is what the recall notice says.
"
Defect Details: The product has fractured causing the front wheel of the vehicle to which the product is fitted to separate itself from its mounting point."
Put yourself in the place of the first ever person to complain that the hub fractured. Do you think he was met with a smile and a replacement given to him without question. Do you think the seller/manufacturer used all sorts of self satisfying excuses like " we have sold hundreds of these and no-one else has a problem", or " You must have hit a gutter". And do you think the seller/manufacturer covered the cost of any consequent damage caused because the hub fractured.
Sideshow, notice that this site is a government site and sellers or manufacturers are named. In many cases the seller/manufacturer is being FORCED to recall his faulty goods.
A trader who has a decent management philosophy regarding the handling of complaints or warranty claims will not find themselves in a public dispute.
