Frustration will be making learning impossible. As suggested, discuss it with the school. But if it is a small, tight-knit school, that might not work.
When I got my PPL at Thruxton in 1964 after soloing, the Assistant Instructor stopped a circuit refresher part way, and said he couldn't help me. Before I noticed it. Another more experienced instructor quickly found my problem, and I was back with the Assistant.
Different people have different learning patterns. I learn nothing by watching an Instructor demonstrate - I need to be hands-on, with the Instructor spotting what I'm doing wrong.
Regaining my PPL after 21 years, I had your problem with one Instructor, fortunately few lessons were with him.
