Bad service / After sale experience

I think we deserve a better service than this, our car which is the XUV300 had multiple problems with a noise coming from the from wheels, which is more than irritating but rather concerning, the vehicle was sent to Mahindra East London more than 3 times and last time we were told that brake pads were replaced but yet the noise is back , when I went to the new premises of Mahindra East London which is Eastern Cape Motors , the lady told me that they dont have history or information since they have moved premises, so there is currently no history for what i was complaining about. My question is how can i big company like then dont have migration strategy or could not have moved Data from one place to the other, I was told I could bring the vehicle , they will have a look and I have to pay for the 1hr labor to do that. I seriously dont understand why must we pay for a return job. if this how after sale ism we are not buying any Mahindra vehicle ever again, even the XUV700 that we were looking at is out of the window now.

Can we please get a resolve on this issue. Can someone who is knowledgeable get the history of this vehicle and sort it out. We cannot continue like this.
