差し上げる humble form

やる can be used when giving to younger people, animals, things.

~てあげる to do for someone else.

These aren’t used when talking (directly) to someone older/above you. As it sounds like you’re doing something for them. It’s better to use the ~ます form of the action verb. ってあげます って差し上げます
