Dear guest,

The products that you were delivered are defected good as far as I got informed from your message. In commercial sales, parties have to act watchful and prudent while supplying goods and making the payments in return. With this reason, they are obliged to act more careful than the customers and consumers.

As for your question; what you can do against the supplier for the defected goods is either terminating the contract, or demanding the products to be replaced with indefective ones. Both for the replacement of the goods and terminating the contract, you have to inform the supplier in 8 days as of the date you got delivered the defective products. You can not demand the replacement or terminate the agreement if this time limit is exceeded unless there's a hidden defect on the goods that you can not be expected to realize in a short while.

Considering that you are dwelling in Australia, it's almost impossible to follow all these transactions and actions on your own that are probable to be started later. You'll need a Turkish lawyer who's efficiently displaying an activity in Turkey.

Hope this helps,

Regards.
