Angry customer -Mileage tempered with, Car cannot be service_ Renault Northcliff 😡😡😡

I purchased a vehicle at Renault Northcliff and took collection of the vehicle towards the end of July 2024 and when I got the car the mileage was just above15 000 KMs. The car came with 3 free services from the time of collection. Last week I took my car in for a service at Renault Germiston and was shocked to learn that when they check on their system using the vehicle's VIN number the kilometres on the car couldn't be correct as the car already went for a service for 15 000 kms in January and the 30 000 one in May 2024 and my car cannot be serviced due to this discrepancy. I have contacted the sales person Thembinkosi Motha at Renault Northcliff and he's ignoring my calls and messages and I even called to speak to the Sales Manager whom I explained the situation to and he since said he will escalate the matter to the relevant people and I still have not had response or resolution to my problem.
