Poor service at Kia Menlyn

I took my car for service at Kia/ Hyundai Menlyn on 21 November 2018. Upon collection of my car I realised that there were discrepancies on the car which I reported immediately before taking my car off their premises. I was promised that the matter will be escalated to the manager for a solution by the service agent who was assisting me. I still have not received any feedback up to today. One of the park lights which was supposedly replaced was not even installed on the car but was I charged for it. No one indicated to me that the bulb could not be replaced. When asked I was told that the cables were not there so they could not replace the bulb. This came as a surprise to me as I am 100% sure that the cables were never tempered with before taking my car for service. The service I was provided with was therefore very poor
