Very very poor service. ******** and ********

I recently took my fard to Nissan Harrismith. Morgan Nissan. On their pamphlet they say they do an inspection or some points check before service. They fid not do this for my car. They did not give me a price list of what was done to my car. I asked them to check my front shocks. They agreed but did not check them. It cost R600 to do points check which i must now pay separatley. When they took my car in they gave me a quote. After service they tell me they dont have fuel filter so they did not change it. But price i paid was same as quote. Now i must pay separate labour cost for fuel filter change. Why was i not told before taking my car that they did not have fuel filter.
