They listened to the call and agreed I was incorrectly advised and they posted the J tier points and Avios into my account.
So it can be done if mis-sold!
The point to note here is that there was a recording of the call so clear evidence. I’m not saying the OP is lying, but the proof is going to be harder to find.
