Removing of spotlights and amplifiers from a vehicle that I bought

I bought a Hilux bakkie from Webuycars Rustenburg branch. It was advertised with spotlights. After I paid and collected the bakkie and my driver arrived home with it I saw that the spotlights were not on the bakkie anymore. I notified the salesman and he said he will asked the mechanic. The mechanic then informed me that they have to remove it due to regulations but will courier it to me. I also notified the manager of the dealer sales at Misdstream Branch and send him a message regarding the incident. Also, tried to phone him and then left him numerous messages. Then upon further inspection I found that the radio wasn’t working and it was working as per report. Then I saw that the amplifier under the passenger seat was removed! I found a receipt in the bakkie with the previous owners cell number and contacted him. He informed me that there was actually 2 amplifiers one underneath each of the front seats and he sold the bakkie with both still in the bakkie. I notified the salesman again and he again said he will follow up. Then I received a message from the same mechanic that stated that the Buyer from the Rustenburg branch said that the previous owner removed both amplifiers before he sold the bakkie to Webuycars. Then I told him that I have spoken to the owner and he confirmed that both amplifiers where in the bakkie when he sold it to Webuycars. He said not according to them and I said I have the proof of the owner and Im going to escalate it to the Manager at Midstream. He told me I can do that and he doesn’t care. So once again I send all the info to the manager their. Even this morning of 13 Oct I send him a message again and ask him if he did investigate the matter and if he have any feedback. Till now no response from him at all on any of my messages and calls. I have the messages from the mechanic and the previous owner that are willing to confirm that all the above mentioned spotlights and amplifiers were in the bakkie when he sold it to Webuycars and left it there. I can supply the nr of the salesman, mechanic and manager if needed.
