Dismall customer experience at Auto Pedigree

I bought my car on 21 January 2020 at Auto Pedigree Westgate where I was assisted by Nicholas, everything went well had to wait for my spare key. Nicholas no longer works there and my queries were transferred to Collen Dube, I've been calling and going to the branch asking for feedback and nothing gets sorted just empty promises. At times I would send a text on whatsapp and he would blue tick me, till today I have not received my keys. I referred my cousin to buy a car and if the sale is successful you get a spotters fee on R1500, I also have not received that as she bought her car in June. Can they kindly give me what is rightfully mine as should I lose my keys or something, I'll be in big trouble and they won't pay for the expenses.
