Can I change my attorney before my chapter 13 plan is confirmed?

I am uncomfortable on the attached message of how my attorney did not communicate to me, can I switch attorneys and how much more would I have to pay: Hi Jason: Thank you for responding to my message. I tried to reach you twice today by telephone, but you were unavailable to speak with me. I left a message with Wanda for Jamie to call me back since I am very upset with how this is being handled. I am putting my trust in your firm to handle agreements to my car and my debts and I shouldn't have to follow up to ensure things are being followed through on. The only reason I called the court in the first place is because I never received a call back from you from last week. I wanted to know if I would be receiving a copy of the approved order from the court approving the agreement, so when you didn't call me back or no one else in your office could answer my question, I contacted the court myself. I take it very seriously about court dates and wanted to ensure that I didn't need to be there. Last week, the law clerk told me no agreement had been made either by telephone or in writing and to contact him this morning to find out if the required paperwork had been received by the court for my hearing and he informed me that my hearing was still scheduled for today at 2:30 pm because no paperwork for an agreement was received. I called your office and asked to speak with you and you were unable to speak with me and Wendy communicated to me that an agreement was made with Landmark based on her conversation with you. I spoke with clerk again, who advised me that you and Landmark's attorney called the court today 15 minutes after I called the court advising an agreement was made, however, the court adjourned today's hearing and scheduled a new hearing date of 5/14/13. My question is this, I am paying you to handle my case, why wasn't the agreement sent to the court in time? Why was a new date scheduled? Am I incurring additional attorney's?
