Have or get

"Usually when you have a boob job, you get these two big blobs in the middle of nowhere,..."

Teachers,

After all this time of learning English, I'm still having trouble with when to use "have" and not "get" and vice versa.

Please help~

Teachers, After all this time of learning English, I'm still having trouble with when to use "have" and not "get" and vice versa. Please help~ In the first clause, you can use either. Formally, we use "have" in such situation when we arrange to have something done to or for us. Informally, we can use "get". The second clause talks about the result and we can use "get" or expressions such as "end with" or "end up with". Formally: "I'm having a boob job." (Arranging to have a boob job.) Informally: I'm getting a boob job." (There, "getting" could also mean "purchasing", but probably means "arranging to have".) Other examples: I having/getting my hair cut. She having/getting the house painted next week. He had/got his car fixed so we can now go away for the weekend.

I [am] having/getting my hair cut.

She [is] having/getting the house painted next week.

These sentences are missing "am" and "is", respectively.
