My name is Patricia Maswanganyi. In or around April 2023 I bought a car from we buy cars in Germiston. I was informed about the engine leakage. I made the payment and took the car home. Within a month a car did not want to start. I contacted we buy cars offices. someone was assigned to help me with my car. I was advised to take the car for inspection and do quotation to fix the car. It turned out that the computer box was the problem why the car could not start. We buy cars representative called/ phones me and advised that they wont be able fix the car. I did not drive the car for long after buying and I paid cash. and I was not told about the computer box problems. How is it my issues now. Please help me resolve this matter.
