Poor Customer Service

If there was a zero star, I'd definitely give that because wow!!! I didn't think I'd be back here to complain about the same thing. I'm truly not happy with Nissan Bruma from application stage😔,I traded in my vehicle dropped it off and fetched my new car on the 12 of January 24,I had a personalized number plate on the vehicle that I traded in, which I clearly stated that I want the same number plate on my new vehicle, my permit was expiring on the 31st of January I had to follow up with the dealer, the sales man by the name of Bheki (works for renault but he was my salesman on the deal) said I can come get the number plate and disc on that day, I told that I knock off at 16:30, yes I live 15-20 minutes from the with him that I'm delayed he did not respond, told him that I'm on my way to the dealer, he called me and he was rude telling me that I should be there because they don't let customers in after 5 because the boss wants them to be gone, I had to go back home because they won't assist me after 17:00. I complained he came here with a "Temp" number plate and license disc while they're sorting out registration of the personalized number plate to be moved from my old car to the new car, I've been following up as to how far are they with the process, Bheki Ngobese said he'll give me feedback last week, texted him this week on Monday because I didn't get any update, he responded saying his receptionist was not in he'll give me feedback the following day which was on Tuesday but I got no response texted him again on Wednesday and today he's still ignoring me. I need that number plate ASAP because I'm traveling on Tuesday I'm tired of the "Temp number plate" I want my personalized one on Monday or else I'll take this matter further because I don't see what's so difficult about proving feedback or rather keeping me in the loop as to how far the process is. I need my PERSONALIZED number plate on Monday.
