POOR SERVICE RECEIVED FROM HAVAL UMHLANGA

My Brand new Haval Jolion HEV had a system failure and stalled 2 weeks after me taking ownership. I was stranded while on Holiday and insisted that the vehicle be replaced or I be refunded as the dealership could not detect the fault. It was disappointing that the Umhlanga dealership has no Dealer Principal. The service received from the service manager and sales manager was appalling, none of them could give me the cause of the fault except to state that the software was updated. Haval customer care has not even reverted after allocating me with a case number, calls and messages go unanswered
