Bad service & lack of communication

I bought my car in 2018 March , being a first time buyer my experience was bad , in 2019 I found out my spare wheel provided was incorrect till date they still trying to replace me with the correct one. We drove all the way from Bloemfontein to Woodmead for replacement only to find out the person (manager) had resigned & no one knew anything. The matter has been escalated to the branch manager Mandie Lategan thought by now I would have my spare wheel but nothing after a more than a month now of waiting. When I call no answer , when I send emails she keeps replying adding people no apology whatsoever I'm currently driving a vehicle with no spare wheel.
