Useless siblings!!

How to deal with siblings that want to turn up at Christmas with loads of presents to make them feel better about the lack of presence all bloody year. I’m ready to go to war and make it clear that they aren’t welcome. They haven’t seen my boy in 9 months and he’s the only nephew in our family, Any been faced with this? Getting married next year and ready to not invite also just so annoying in and out of his like life a yoyo and no texts or calls to see how he was.
