Terrible service from BB Nissan Sinoville

the car stopped on my mom Tuesday around 08h00 on her way to work, the first thing she did was send me a call back as she had no airtime and requested me to call her insurance company (King Price) for assistance, i then proceeded in arranging for her car to be collected and taken to the nearest dealership, which by the way is the same dealership the var was purchased about a year ago. the car was there Tuesday 10 April before midday so it could be assessed. i called later that day to find out what the progression of the car was as well as diagnostics and was told that they are first dealing with booked in cars and that they will attend to her soon. It then became Wednesday and we waited feedback till i call in the middle of the day to ask about the status of the car, i was then rudely advised that they would call once a technician has looked at the car. the morning of Tuesday 12 April around 07h00 i got a call from a lady in service (lakisha) or something that it is infact the clutch that is messed up and can i give them permission to strip the car (which would take 3 hours) and then they would come back to me with feedback telling me weather the warranty would cover and if not, what the quote for the service would be. i got impatient all day but decided to call the dealership around 16h00 to find out what was the progress of the car, i asked to speak to manager directly hoping for a speedy and solid response but the guy was just as rude as the service lady, even mentioned that he doesn't even know he is talking to me because i am not even the owner of the car, that time i was the 1 called at 07h00 in the morning, i could even hear it at the end of our call before i hung up that he was somehow talking about the call prior to the hang up (such will be revealed in the call recordings, should they even have them) i intervened in all of this because my mom called me first and i decided to try deal with this ordeal, from calling the insurance company to checking the progress of the car with dealership. (voice records from both the insurance company and the dealership will prove the above mentioned, i have also maintained the times of the calls)
