Vodacom insurance access payment

My iPhone13’s back cracked, and luckily had insurance with my Vodacom contract. The Real Repair company that handles Vodacom repairs notified me that they have no stock to repair my phone. I called Vodacom and the lady that I spoke to suggested that the devise to be wright off, and that they don’t have the same IPhone 13 Pro in stock, therefore my option is either to go for a 13 Pro Max or 14 Pro similar in size than my old phone. I said that I prefer a smaller size phone, which will be the 14 Pro then. The Lady said that the estimate replacement payment for the replacement devise would be around R3800. When I collected my new iPhone 14 Pro, I was told that I also have to pay an additional amount of R2500 because I have an newer/updated phone. This was not communicated to me, and since Vodacom don’t have stock for the exact phone that I had, they left me with no other choice than to take a newer version and expect me to pay up. This is injustice! My repair and claim numbers are the following; TRRC-040794 CLM***
