Resufal to repair projector within warranty

I booked my PA1000 projector at Makro for repairs on the 13th of January the projectors turned on but did not respond if you tried pressing buttons on the remote or on the projector itself thus was faulty. After 3 weeks of waiting I was told that my projector has water damage and that LG will not repair my projector even though it is still within the warranty period. I have been a support of LG products and I have bought 3 LG projectors in the past and I will be dissapointed I LG decides not to repair/replace a product which is within a warranty period and there was never any water in my house where the projector is kept as I have used the same place for all my previous LG projectors which are all still working. The repair reference number I received from Makro Wonderboom is ***.
