I have become frustrated and disappointed with my flight instructor
Don't let your current instructor ruin your enthusiasm for aviation.
You paid for flight training service and you're experiencing compatibility issues with your current instructor. Approach the ATO and file a request to substitute the instructor. Hopefully, the new one will be the right match for you.
However though, make sure you have credible arguments to substantiate your request to opt for another instructor. Elaborate your criteria for a suitable instructor and work with the ATO to address that.
With the proper attitude and approach, you should be able to proceed with your training and achieve your target.
