Disappointment with Mercedes

I’m so disappointed with the service I’ve received from Garden city motors, the Mercedes in Pietermaritzburg. I purchased an A250 AMG in November 2024, with less than 6 months of driving the vehicle I’ve been told there’s a problem with the gear box that requires R14000 to be fixed😭 I don’t understand how this was not picked up before the vehicle being sold to me. I’m so hurt and dissatisfied with the service I’ve received. What a **** 💔
