Bad customer service from MTN Insurance

I bought a handset Iphone 14 256 at Menlyn MTN. Last month on the 26th March I lost my fone and I have been going back and forth with insurance busy with the claim. On Friday the 21st I paid an access fee of R1980. And they confirmed that the handset would be delivered in 3 working days. Today Courier IT delivered the handset and when I opened it the color was different. First of all they asked me so many times to confirm both the capacity & the color of the phone. I immediately called the insurance and told them that I only opened the box but the did not even switch on the handset. I spoke to a lady called Gift and she said that as long as the box is opened then they cannot take responsibility of the wrong color. I should have reported this before opening. First of all the delivery note they had provided did not specify the color of the fone but only my details, the model & the capacity. I only realized this after opening the box and turned the handset. This lady tells I should have noticed this color change before opening and I asked her "how was I to see this without opening if they as the providers could not see the difference". I feel they should have atheist informed me that they could not find the same color before sending it. Or given me options so I can choose on what's available. Also, if the policy is I cannot return the handset once opened I think thet should have told me this and I would have asked that they deliver it to the nearest branch so I can collect & sign for something that I know is correct.

This is absolutely ridiculous, I don't work with phones how was I supposed to know the color was wrong? I am paying a lot of money to be treated like an illiterate .
