BAD After service sales

Purchased a VW6 GTI towards the end September 2015 with much difficulties. Firstly the salesman insisted that we work through NFC which they declined (He advised that others also declined) I then myself called Wesbank which they advised that no application was submitted against my name so i personally app****. Then with conditions that the passengers sun-visor sensor had to be replaced, i inquired but they where still waiting for the bulb. I then had a issue with the consuming of oil, i had to throw in 1punt for less than 1000km(monthly) i then requested to deal with the manager and he advised to bring the car in which i did,he claimed that theres nothing wrong but after the second visit it was perfectly normal,1 punt after more than 2000km.I then called the manager after one month advising that im still awaiting the sensor light and he forgot what i was speaking about, I refreshed his memory and advised that the wiper is perished as per the service receipt that they had done before I purchased the vehicle, he advised that he will do a follow up and i can bring the car in,its a month later again!IM NOT HAPPY WITH THE SERVICE RECEIVED and will be bringing up the consumer protec. act
