Go a bad instructor, get rid.
Qualify this comment though - take valid criticism on the chin, and don't become an arrogant pilot, else you will kill yourself.
You need to the schools for yourself to see what is right for you. Don't be taken in by either marketing, or doing the training at the cheapest location - neither are always the best.
You need to learn from experienced instructors at that stage, so choose somewhere that gives you that best experience and instruction, instead places with limited instructors who have few flying hours themselves.
