No wise purchasing decision

I bought the spotlight in February. Then it was too cold for me to hang him. In the summer, I did not need it and attached in July. He worked then to October.
It switches continues - but only a few will go to LED - almost dark.
The supplier responds very dry:
The burden of proof - no guarantee longer (6 months after purchase).
So I should hire an appraiser to possibly come to my right.
Again learned something: The five euros, which I save in relation to the construction market in the beginning come to me are expensive.
No good customer service and obviously nothing durable or high-grade material, which is very far from the promised hour numbers.
