27 Days later : No feedback or refund !!!!!

I bought a car from the JHB South branch 13 March 2025 and the DECRA report indicated that the air con was "VERY GOOD" indicating that the air con is working. The sales consultant Zanele was very helpful and lodged the issue with ***. I took the car to diagnose the issue with the aircon as per instruction from Zanele. On 19 March it was concluded that the air con only needed to be re-gassed, this was then done at my expense to the value of R632-50. I then submitted all the documents to Kimberley Mngomezulu who the assigned the case to Grace Ngwenya. All docs was sent threw again on 7 April. To date no one is coming back to me with feedback or the payment that needs to be made to me. I send a follow up email again 10 April and again today 16 April to Grace and Kimberly with no reply. I then phoned your customer care number ***, i then requested to speak to a senior manager in the customer care department but was refused and told THAT ALL THE MANAGERS WAS NOT AVAILABLE !!!!!! They then connected me with Grace that is handling my complaint, I then told her that I want to speak to Amanda Fourie and not her due to the lack of any feedback from her side. I then asked her if she received my e-mail today regarding feedback that I requested, SHE THEN TOLD ME THAT SHE HAVE NOT YET CHECKED HER MAILS TODAY, THE TIME BEING 13:15 !!!!! My mail to her was send on 16 April @ 8:23am. She point black refused to connect me to any senior manager and placed me on hold for 35 min. We Buy Cars can pay out customers in a matter of minutes for huge amounts of money but they are unable to pay my R632-50 witch I am waiting from 19 March already..... 27 days later !!!!!!!!!!!!! And then Grace indicated I will have to wait an extra week again. THIS IS UNACEPTABLE !!!!
