Datsun go cvt parts hard to get, long wait

Hi, I have bought a 2020 Datsun go plus cvt, Nissan stopped making this car, promised us they will still have parts, I am waiting going 3 years for parts, the manager Mr kimolin is aware of my case, a simple window mechanism and rubbers, imagine if I need the automatic gearbox, still under warranty, eish, they should refund my money if it's a problem, car is paid off. They keep speaking lies by saying they ordered wrong parts, becareful, even had problem with my front disc pads, was making funny noise, I reported and waited over a year, they lie and told I need to replace them which has over 60% life on them, when I told them I no they lie, they replaced the brake pads at they costs, fitting in Renault front pads, I sent the manager many what'sup messages in this regards, no reply, no joy for parts.
