Donfordmotorad don't want to repair my bike

I bought a bmw s1000rr by biketique the 15sep 2015 I took delivery the Friday at 5pm I left Saturday to a rally my gearbox broke I took the bike back the Monday they sent it to bmw Donford in capetown my bike was there 3weeks I got it back my bike wasn't washed.just so dirty my clutch lever didn't feel the same but I thought maybe it must feel so because the gearbox was a problem it's my first time on a bmw s1000rr my clutch broke after a few weeks I took it back and now they don't wana repair it they saying some1 worked on it but they were the only ones that worked on it I didn't even ride a 1000kms since I have it. My radiator is also Broken they say I apply brakes to hard! I had a suzuki gsxr before this bike and I had no issues with it. I took my brothers s1000rr in for a service at donfordmotorad I asked them is there a aftermarket filter in they said no it's a std 1 when I fetched the bike the chain wasn't wax they gave me a empty can to do it myself.i took the bike away to fit a aftermarket filter in then they told me there is 1 in it was so dirty bmw didn't even clean it but they say there's a std filter in when I told them they said they don't check that on a service !!!!
