Hyundai i20 1.0TGDI

I am not happy at all last week Tuesday 2nd September my car was towed to them by Msure from motolek and we spoke to vash on the phone me and Calvin from msure tell them why we bring the car to them, The car is on warranty booster with msure and hyundai and the only problem on the car is oil cooler and the reason I am saying that it’s because the car is driving perfectly no engine light or overheating but the car is mixing oil and coolant so till date I don’t have my car with me and haven’t heard anything from hyundai Lenasia when I ask Vash she’s says technician haven’t said anything to her so I guess I’ll still have to wait and when I ask for a courtesy car they tell me they don’t offer that.
