Poor client service

I took my car in to tangawizi motors for a question on why my phone link is not working. Unfortunately the service was not up to standard. It seemed like 1 lady had everything to do. In the front desk, there are 3 positions. Only hers was occupied. I had to wait over 20 minutes to be acknowledged. I asked about the phone link with a senior service technician, and about a software upgrade. I told him I bought the car second hand. His words to me were I should have checked it was working before I bought the car for the dealership. He did not know I didn't buy it from a hyundai dealer. Its hyundai software and the dealer i bought it from would not been able to assist. He did not even bother to ask where i bought the car.The look on his face was that this problem was beneath him and did not want to assist. I was shocked at that attitude from the technician. The service was terrible and I'm already thinking selling this car due to the poor response and empathy I received from tangawizi motors
