Mediocre Customer Service

I bought a brand new Landwind5 flagship last year in July and I several complaints. First had such a difficult and arrogant sales person (Ridwaan). Then I had a couple of minor issues with the new car and I was impressed with some of the aftersales people that were able to resolve some of the issues. However I discovered a defect in the vehicles roof lining in November 2019. I took the vehicle to the Ruimsig branch where I made Candice, in the Service department, aware of the problem. She promised to arrange for it to be replaced by their affiliated panel beaters. Ever since I have been calling Candice to following up on this matter and I am still without a resolution. Every time I call Candice I get the same empty promises. Recently she is always unavailable for last two weeks I have been trying to get hold of her. No one else is able to assist either in her absence. I am regretting my decision to switch from Toyota to JMC?
