Bosch Northcliff

I took my car to bosch Northcliff as it was recommended by the company that warranty with msure. The car was leaking water only and had no warning sign except for the rear break light nor was it over heating. I dropped off the car on Wednesday afternoon on December the 7th 2022.i asked them for a diagnostic report and asked them to update me beforehand as what the issue was so that I can claim from warranty and make provision should there be a short payment. Thursday I called their office to follow up with them and they said they will revert back to me. They said they picked up a few things on the car and tried claiming from the warranty which they declined and i was shocked cos the car was booked in for a waterleak only. What's frustrated me was that they went to msure before talking to me about what they picked up and had already submitted quotes on Thursday and Friday. Friday afternoon I sent a WhatsApp stating that they need to attend to the water pump only and they failed to give me a final quote for the water pump and light bulb and had already submitted a claim from my warranty. On Monday I got quotes from BMW which were cheaper than bosch prices and they are the manufacturer I don't know where bosch is sourcing their parts from when the actual manufacturer is cheaper than them and are supplying me with genuine parts. Monday afternoon the 12 I told them not to go ahead and repair the car and I will pick up the car from them as this was a costly exercise for me to use bolt and i was late for work. I got a call from bosch stating that they fixed the car on Monday afternoon and charged me am extra amount for the replacement of the water pump and thermostat. This is so strange considering the fact that the i told them not to go ahead with the repair and when i called them on Tuesday they said they took the car for a test drive,which simply means that they replaced everything om Tuesday. I got invoiced for a light bulb that was not replaced and anti freeze. I lodged the complaint with msure and today I was shocked to learn that msure does not see anything wrong with my entire experience and they even insisting that the thermostat was replaced by bosch for free but it wasn't on the final invoice.
