Rattle in Suzuki Swift dash, reported since 2020 and it has not been fixed by Suzuki Menlyn Penta

Good day, extremely disappointed with the service from Suzuki Menlyn Penta. I purchased my Suzuki Swift in April 2019 and from just before Covid in March 2020 I made them aware of a rattle in the dash, every time my car had to go for a service I informed them, the one bloke from the workshop (Johan) even drove with me to listen to the noise. It has never been fixed. So this year when I took it back for its service I again mentioned it to Theresa in the workshop. I am livid, they now want to charge me to fix it. I told her that she can go and check that I have reported it each year whilst it was still under warranty, now that the car is out of warranty now they are prepared to fix it at a cost. I was really annoyed by this. Theresa said she would speak to her manager., I then called to follow up a few times and each time I was told that he first needs to go through all previous invoices to make sure I had reported it. Nobody gets back to me and I am very disappointed in this. The rattle has been there for 3 years already and it annoys me each time I climb in the car.
