Try it again

I returned a battery charger on 31/1. The first questiong from Customer Service rep was 'you bought this in September and only returning it now?' This made me irrate as I can't charge my car battery when it's not flat. Either way, I brought this charger as it never charged my battery even by 1%. It was tested by Daniel and he even tried to use different fuse sizes which were a different size enclosed in the box. He confirmed the charger will work now. Why must I prove that I used this product to no satisfaction? It's me against Game now and their charger. No option given for an exchange. I feel like a puppet on strings. Now I have to go back to the same person and explain the same story again? I had to run a car battery flat in order to prove myself and, once again I had to pay to have the battery recharged. This product is letting me down. I can't keep buying fuses. Is this how you treat customers who query the quality of your products?
