unhappy client

I took my car for a normal service in December. 3-5 days later there was smoke coming out of my car. I went back and they told me i must pay +-R5 000.00 to fix it because there was water leak. i agreed and when it was there i was told they discovered something so the bill will now be +- R8 000.00. 2 Days later i was told water and oil is mixing because top casket did wat wat wat wat. then later it was oil leak. I eventually paid R15 000.00 to have the car fixed. 15 KM later i taking my car for a normal service then Boom there is a water leak this time.They need me pay extra R2 000.00 to diagnose the car and they will be able to tell me how much it will cost to fix it.

No one can tell me wt caused the leak. Just like last time this bill will be just as high. This car i bough brand new form the same dealer and have been taking it to the same dealer every service.I complained to they complain but i got the same response that i must pay yet again. This is ridiculous
