Worst customer Service ever experienced

I purchased my car in in Dec 2019. To date the service I have received has been appalling. I took my car in for a service on the 15th December and its now the 23rd December and I still have not received my car back. I have called the service centre as I was suppose to receive it yesterday after multiple promises and no one even bothered calling me back. No one cares and every time my car goes in, which it has previously to fix the brakes and replace the battery because it didn't start, I never seem to get my car back on the same day and no one cares.

Havals service has been the worst I have ever experienced. I can't even sell it back to them because ill owe the bank over R60k, which shoes how poorly it depreciates in less than a year.

Earlier the year my car didn't want to start and they wanted me to pay for a new battery for a car that was 6 months old. I had to fight and threaten taking this further for them to agree to pay for something that was clearly a Haval issue.

When I purchased my car they sold a netstar tracker to me and it was never installed. It became my problem to resolve during a Christmas season. The car was not registered so netstar battled to put the tracker on my name. This was only resolved by the new year. Almost a year later and I still don't have netstar details because I gave up on the process.

Now on a year later I'm sitting with my car in a Haval service centre that went in for a 15 000 service and to check the aircon and a week later I'm still waiting. The service manager tells me that he can't help me with a car to drive in the meantime so what happens....I need to throw my customer service toys out the cot again to be heard. The dealer principle calls after I complain and sweet talks me and yet here I am a week later, hoping someone calls me to tell me my car is ready.

What am I suppose to do besides want to give this car back.

Please can someone get back to me and provide some sort of decent customer service experience.

1 year down on owning an H2 and I regret walking into Haval.
