KIA SPRINGS COMPLAIN ABOUT THE CASHBACK DEAL

I bought a KIA SELTOS at Springs Kia on August 12, 2023. I went there because I was in the area. my main idea was to go look for the car and find out if they also have the R50 000.00 cashback as in Nigel Kia. On our( my husband and I) arrival we were welcomed by a lady called Kenielwe. She showed us the car and we were impressed. We asked her about the R50 000. 00 cashback and she said yes they have it. She added that we can take it as cash for our use or use it to pay for our installment. She then asked us to give her some documents to check if we qualified. She said that she would call us if everything went well. She called us the following day that we could come on the 12th of August 2023 since it is approved. when we were with the finance lady we asked her about the R50 000.00 cashback she said we must not believe the sales person they do not know about finance. We took it lightly and did not believe her. we went on and signed the deal. After a week I decided to call Kia SA about the matter just to find out if the deal was only for specific dealers or for all of them. the guy was very surprised he said it was for the dealers and asked that I call Kia Springs again and ask why was I not given the deal. He gave me his cell number to give him feedback. I called Kia Springs I was sent from pillar to post until I dropped the phone. I phoned the guy and he put me through to the complaints department the lady kept me holding after hearing my story. She never came back to me and I dropped the phone. I was advised to contact the MIO SA Motor Industry Ombudsman which I did. After filling in their forms and sending them my complaint they acknowledge receiving it. I waited for their response for about a month until I emailed them to enquire. their response was the case was all closed and sent me the letter.
