NO AFTER SERVICE WHEN BUYING A NEW TOYOTA

I bought a brand new Toyota double cab 4x4 at Whiteriver NTT on the 24th of March 2021. I was on my way back to my house in JHB when I saw my radio screen was faulty making strange lines over the screen. I then took it to Delmas NTT on my way home and they said it will be better to go to East Rand Toyota because they are closer to where I stay. The guy at NTT Delmas said it's a faulty radio and needs to be replaced. On the 27th I took it to East Rand Toyota and they also confirmed that it is indeed a faulty radio and needs to be replaced. They said they would order the new unit at Toyota SA and will let me know once it's there. After a week they came back to me and told me they cannot replace the unit because there is no stock in SA and they need to bring it in from Japan. 3 weeks since I bought the vehicle I am still sitting without a radio in a new Toyota double cab and not East Rand Toyota or Toyota SA can give me a date when I will receive a new radio. They said it can take up to 12 weeks but no one can say for certain. I cannot believe that Toyota sell cars and bakkies but don't keep stock on products like radios. I was always a firm believer of Toyota but perhaps I should reconsider. I bought a new bakkie to avoid problems like this
