Poor Service delivery to the customers.

I bought my Mazda 3 active last year April and in November I got a car accident and my insurance approved my claim very quickly without giving me problems. Today I'm helpless and stranded with no transport because of Mazda dealership. The order was placed around 12 December but till today I'm still waiting for my Mazda 3 parts with no ETA date on when they will arrive. They promised to deliver all the part at the end of January, now some part come by 1 or 2 every month. March is the 5th month without my car. Everyone keep telling me that my car is a new vehicle therefore there is no spare parts here in South Africa and some are using Covid-19 as big excuse for my part not being delivered. All I want to know why do you sell cars that doesn't have spare parts here in South Africa because we are really suffering. The only time when Mazda goes all out is only for sales and once you purchase they don't care about their customers. I really don't want to lie, Mazda was my dream car but now I regret buying this car and I will never recommend anyone to buy car from Mazda and this will be my last car to own and I will make sure everyone knows about your poor service . Mazda is a **** we are paying monthly installments for nothing. This dealership only cares about Money and I don't know how do you build trust and loyal to your customers if you are doing like this. I hope my issue will be attended quick as I'm still your customer.
