I would not recommend it, as you will most likely need to pay the current agents commission as well as any new agent you switched to. If they submitted an offer and showed the property to you, there is a clause called procuring cause. The current agent you are in escrow with has earned her commission based on procuring cause. I would recommend speaking to your current agents broker to try to resolve any issues you may have.
Have a great day,
