NIsan cannot supply spare parts for NP 200

I ordered a pressure switch for my Nissan NP200 on 12th of November 2022. After numerous enquiries by March 20323 I got an estimated time for arrival of 5th of May 2023. On the 5th I enquired again and only today I got feedback that the part hasn't left the manufacturer overseas yet. This is terrible. My Car's power steering is leaking oil and I have to refill everyday and is costing me a about R50 per day to refill the oil. I do not not know what to do anymore.
