Customer service is non existent and no intention of helping

I have been without my contract SIM for almost 6 months. I spend most of my time outside of SA but require my sim to be on. I got a new phone and needed a new esim as my previous QR code doesn't work on the new phone. MTN SA has no intention of helping me to get me a new qr code for my new device or even post a physical SIM to my registered address. On the business side they will quickly send a new esim no questions asked but on consumer side they will not budge. Please if someone from MTN can assist me in this situation, as I will not be back in SA till at least mid next year.
