Struggling to get any kind of service from Cherry

I bought a Cherry Tiggo from Boksburg branch end November 2015. The vehicle was not in an acceptable condition when the keys was given to me, no handover was done. i complaint on hellopeter and was promised everything will be sorted out after calliing shane on a weekly basis because my calls were never answered the car was finally serviced on 12 January but not everything was fixed as Shane forgot to tell the service department that there is also a problem with the petrol Gage. i spoke to De wet the day after as s my servise book got lost( no Surprise) he informed me the would order the part and call me. I have not been called since the 13 th January i left 5 messages on Monday 8 February and also 2 this morning for de wet to call me back and still have not received any updates. It been almost 3 months since i had the car and the condition of this vehicle is still not acceptable..
