what happens if BOA closes an account and puts a share fraud

BOA closed an account and put share fraud on the EWS I am just understanding all of this.... They did this before I gave them documentation. Their risk dept is very difficult to deal with and I have contacted the branch managers who are not willing to reopen account even though I've given them letters from the banks showing fault regarding checks submitted and BOA only submits once. Should I send in the dispute for EWS without speaking to a lawyer? what happens to open credit and accounts? This is a tragedy... help
