Unhappy client.

Hi my name is Mthunzi Mazibuko ID no 8103205859089, cell number 0716850768 my problem is I bought a car, BAIC X55 from Sentracor in Ladysmith, the problem is that it doesn't have a trunk COVER and the things in the trunk are visible to everyone, I went back to ask about it and they told me that it is sold separately, the thing that confuses me is that since I started buying cars I have never heard of that thing. What shocked me the most was that they said it costs R3150, I really don't understand this.
