That seems a sudden change of terms and conditions and they're free to do that at any time they wish to do. There have been issues with them in the past and they're different from yours. So, if you can contest that again to them and try to explain that you should have that points stuck on you, they'll just direct you to this T&C that they changed last March. I'm sorry what happened to your points OP but still try out the suggestions that were tipped to you by our fellow members above.
