In shock with vw

I bought t5 kombi bus 2011 model in 2017 November on the clock was 195000km and just after 4 months April 2018 I had problem with the ignition starter and went to vw soweto were I bought the bus to seek help and because I had extended warranty which I was offered by motorite..when I was to use that warranty I was later informed on the 9th of April that my warranty did not cover for ignition lock to be repaired I was in shock and devasted then I ask vw soweto since I had the car and took it from you what can you do to help me as I use this car to go to work and I really need it as I stay far from soweto vw...the manager Name was clairens with an attitude looked at me and offered me 50% to the damage and I must pay 50% of which I was in shock because I just had the car for just 4months it's not even over 6 months or more this was bad experience as the vehicle is at vw soweto even now I also seek help and advice on what to do from now...why is it when you buy vehicle you get best service but after the sale is made they just turn their backs and walk away....
