Most gyms you go to offer personal trainers. If it's a corporate run facility like Ballys or 24hr fitness, they'll have their own trainers instead of 3rd party trainers. When you buy a training "package", you pay for X amount of training sessions. There's normally a selection of trainers to choose from too. If the one you have is a problem, ask for another one. You'll probably have to start 'fresh' with the new one but it'll probably be better than doing the same old thing.

I personally can't see what your current trainer has in mind for you as you haven't given much detail about it yet. It's hard to criticize what they're doing at this point. But the bottom line is if you're not happy, get a new trainer.

Good luck!
