Hatfield VW Melrose Not Taking Responsibility -Car day-time light faulty

In 2021 October (very recent) I bought a car from Hatfield VW Melrose, its only been four months and im so dissapointed with my choice. I took my car for service for the first time and the garrage I went to discovered that my day-time light is not working because there has been "work" done on it previously by welders/ mechanics. The service garrage then sent me a quote for fixing the light and I dont have an insurance to cover that as I did not buy the car hoping to find the faulty with the light. The issue of the previous work done on the day -time light was not explained to me, it was never mentioned that the car had been involved in an accident none whatsoverr..hence I dont feel accountable for it.

The manager from Hatfield VW Melrose garrage is surpised that another garrage picked up the issue and that the waranty wont pay when they know very well they sold me a car with a faulty- light. Thats the email i got people " Dear Mpho, my manager and I were both surpised"!! shoook!! how conveniet! This car came with so much isses, the front wipers were not working, back wipers , brake issues ( of which they're always willing to fix). Now because its a big issue which requires a lot of money to fix they're trying to run away from it. I wonder what else am going to discover in the next months cos its only been 4MONTH and this car is giving me headache!! I will never ever recomend this garrage when purchasing a car, ****s!! ********S!! so **** dissapointed !!!
