Hyundai Bryanston fails at car service

I am sharing my experience about service received in Hyundai Bryanston, my car was in for service and communication was intact with the dealer, I was charged R1400 to fix park lights, next day I realised that the park light by the driver’s side was not fixed, I reported the issue to the branch and I was ignored i then reached out to their head office in bedfordview at first they pretended as if the were attending to the matter to dead end as referred me back to the branch well i’m not the type to notice something wrong to my food at a restaurant and send it back to be corrected hence I was frank with them to refund me. Millicent who was kind from my previous service to have kept my service book took advantage of her kind act and has ever since speaking to her manager regarding my refund. This is limiting me to drive at night without a light and has exposed me to constant fear of the JMPD as my car is now not road worthy. To Hyundai bryanston I want my money back for the false service
