am very annoyed and dissatisfied with the following points: Before the 60 km maintenance I contacted the after sale service here in Egypt to ask whether it's ok to change the oil outside before doing the maintenance. I have been told that it's ok as long as use total quartz oil. So I did. Few days after I went to the branch where I reserved the maintenance. No check up about the Engine oil or its filter were done there. After only about 500 m my car suddenly stopped and was not working. I contacted Renault and I had to bring it to Obur main branch to check the motor!! I have been told there that the level of the engine oil was low which caused a damage to the motor and that this is the risk of changing the engine oil anywhere else. My 2 concerns are: 1.Why didn't you tell me this from the beginning when I called 2 times to ask if this is ok or not. Why can't you direcently tell your customers the risk of such an action and that it's not recommended. How come you are telling me this after a damage in the motor occurred.. Please keep in mind that all calls are recorded. (Calls took place few days before the 6th of February) 2. How come when they did the regular 60 000km maintenance they didn't check for the level of the engine oil although the person that is handling the complaint just told me that this is obligatory. (Maintenance order is available) Now such a big company with international standards is explaining the risk after all what happened and not before. As a client that was doing everything in Renault with trust (all the maintenances) I am really disappointed with the unprofessional way you dealt with me. Waiting for your response Best regards Nagla F.Soliman
