Extremely bad service

On 15 Nov 2022 I called Imperial select to get assistance regarding a spare key that was never given to me when I bought the car in 2017. I spoke to JP Harmse who requested that I forward him emails of the previous people I spoke to regarding the matter (which I did) and he promised to give me call me back as soon as he receives feedback from the used car manager. A week later, 22 Nov 2022 I sent another email requesting feedback because he hasn’t said a word to me but until today he still hasn’t responded, I still don’t have my spare key despite communicating with the dealership. I even asked if there was any more information I could provide to assist with the matter but he never replied. I need the spare key of my car and would not accept any explanation from these people because it’s clear that they’re taking me for a fool. I will not accept any telephonic communication with them because then I will not have any proof, the only acceptable thing right now is them advising when will I be receiving the key, nothing more.
