Poor service, always making excuses and taking no responsibility

Booked my 2020 Duster in for an aircon related issue on Monday, 10 Feb'25. The following day, the vehicles battery was completely flat after being checked when booked in the previous day with no indication of a problem. I had to replace the battery as the dealership took no responsibility even though there was the possibility of foul play regarding the battery . During the battery replacement I noticed some oil on the engine cover. I then discovered that during the vehicle servicing the previous year a oil leak from a breather pipe was identified and a note made for client to check oil level with no proactive intention to repair a vehicle under warranty which would be expected from a branded dealership. The faulty aircon sensor identified on Monday, 10 Feb'25 was replaced yesterday, 17 Feb'25 and unsurprisingly the aircon problem repeated itself today, 18 Feb'25. Renault Pinetown in my opinion does not seem Customer service focused, always making excuses for their actions and taking no responsibility.
