Hey, I'm sorry about that. Have you by any chance spent the COD points on any shared titles such as Black Ops 3, Infinite Warfare, Black Ops 4?
If not and you are still missing the COD points the best suggestion would be to head over to official support with proof of purchase. They will be able to look into the situation and assist further as soon as possible:
