Toyota customer care - Poor Service

I purchased a Toyota vehicle in 2022. Every apect of the sale i would rate as 12/10. The service from the dealership could not beb faulted in any way. The vehcile was as expected a trustworthy reliable Toyota. It came as a surprise when shortly after receicving vehicle, i noted that every now and again the centre infotainment unit goes blant for a few seconds after engaging reverse. Since not happening very often, I dint think too much of it. I at the time reported to the salesman and the Genral Manager of the dealership. On the first service, I reported the issue which by the time was a little more frequyent than initially. The response from the service team was that I record these instances with my phone. Unfortunalty, this does not happen all the time, so dod I take out my phone and receord the screen every time I start, I should think NO. I Raised the isue with toyota customer care on 15/04/2023 with ref *** and was told an Angelelique Vermaak will get back to me. Nothing. I raised again on 29 December 2023, again Angelique Vermakk. Nothing. Again on 08.01/2024, this time a Collen Phiri abd Njabulo Mcambi were to contact me. Nothing. I called on 9/01/2024, and was assured that either of the affore mentioned gents will get back to me. Nothing. I sent an email on 11/01/2024, advising that if i contineously ignored I will also report this on external platforms. Toyota Customer Service never responded, obviously, do not have the time of day for a little irritating customer, them have thousands more and can loose a pety one.
