Bad Service From Santalia Singh and her manager Chantal Plater

I had purchased a Suzuki Alto from a Salesperson named Santalia Singh. She advised me that the car was in great condition and it was pre-owed, The car had a back smash that was filled with body filer and spray painted and this was patched up very nicely. i came to know about this after i tapped into a light pole that this car was patched up and sold to me. i was a first time car owner so i was taking all the advise and directions from the sales lady. she had then **** on the documents that i had picked up the car at 25 000 KM however i fetched the car at 29 000 km on the clock. she had messed up the service and maintenance plan has the took the car for service at 27 000 KM on my service plan before giving me the car, which the service and maintenance plan only cover me to 50 000 KM. this means that i could only take the car for 1 service. i have been having problems with my gear box and the maintenance guys dont want to cover me due to me not being able to service my car because there was no plan to cover me. i did go to the Pinetown Branch and spoke to the manager Chantal Plater who had promise to assist me and she understood that Santalia had made mistakes on the documents, so i agreed. i have been emailing Chantal for the last 2 months and i have not been able to get through to her. i feel like i have been ripped of for alot of money. i have bought a car that i cant use properly now because of the issue with the car. Chantal i have also tried calling you a few minute ago and i have sent you a whatsapp as per your request on your voice mail message. Please can someone , anyone help me as my money is involved.
