No attorney can force the opposition to comply. Sometimes that attorney can get the opponent to pay the attorney fee and costs as a result of the noncompliance. Being fully prepared for trial six months out is NOT the norm, especially when there has been non-compliance.
Emails are a terrible way to communicate with a lawyer for matters of importance such as strategy. Schedule an appointment to meet with her in her office for 15-20 minutes to meet face to face. If her explanations and abilities seem inadequate and your expectations are not unreasonable, then ask someone else in the firm to transfer the case or hire someone from outside the firm. The latter would probably be better, all things considered.
While it is not inappropriate let me make a suggestion. Schedule a meeting with your attorney and fully explain your concerns. Perhaps there is some misunderstanding or something that just needs to be better explained to you. Make sure your concerns are well founded. If you go to a more senior lawyer with issues that are really not problems, you may be looked at as more of a problem and if you have legitimate concerns in the future they may not get the attention they would otherwise deserve.
