Bad after market customer car prestige motor group pinetown (GAC)

I would like urgent help, as once a customer buys a car they don't get urgent assistance as the time they are searching or buying.

My partner bought a grand i10 2023 red (pre owned) in color at pinetown gac. She had a flat tyre and then we found out there is no lock nut. She was on the freeway and also unsafe informal settlements... I have called the dealer. I had to now leave work to assist her. Bare in mind she is new driver, new owner, and female. Managed to plug the car and took it to a wheel place to check tyre, but the tyre is damaged on the side so have to replace it. When the guys take out the spare they find a, huge lump on the side of the spare wheel. Now this dealer is just too busy to even help me.. I now have deadlines I'm missing at work because they have no time for me and I can't give a female, new driver to driving around with such a spare tyre. Even worse insurance have a fit on this.. I'm already an hour late and had to drive to the dealer ship to get some help which 20 km + from where we are..i was hoping the manager would be looking into this as I found him in the morning, I was by time while on teams meeting only to find he has not even looked into this matter. I'm starting to regret on the purchase of this vehicle here.

It's been 2 days car is not sitting have to pay for Uber rides as tyre is not safe to drive and insurance won't pay. That manager just didn't care in the world. They just want to make a deal and go. I had to pay to get a lock nut that fits that car others wise they have to break all.
