Do you even have my car?

My Renault kwid is exactly one year old and on Friday 3 March 2023, the exhaust fell off while I was driving. The car was towed to Renault Sambezi on Saturday 4 March 2023. Since then I have had NO feedback from them. I have phoned about 5 times and they keeps saying they will phone me back, but no one gets back to me... I actually cannot believe it... Is my car even there?
