The Tax Club Unauthorized withdrawl from my bank account New York New York

I too started my business and recieved a phone call from Brandon ext 5320 at The Tax Club who explained to me the tax services provided. It sounded good but I didn't have the finances at the moment to invest because of the start up cost for my business. He explained it was not a problem and that he could do installments, but I was not ready to commit to that either. Unfortunately, I did trust the situtation enough that I let him put my information (i.e. my VISA debit card info) "on file", as I had planned to enroll at a later more economically feasible date. 2 hours later his supervisor called (whose name I do not remember) pressuring me to authorize a withdrawl now..he even stated that he had access to my account and could see that my balance was high enough for the first installment to clear. I explained to him that the balance may appear as if there is enough money in my account but I had already written checks that pretty much accounted for the entire balance. He continued to try and pressure me into giving him a date to withdrawl the money, which I refused to do. He finally settled on scheduling a date and time to talk with him and Brandon again (the following tuesday at 11 am). After the pushiness of the supervisor I questioned the authenticity of the company and my level of trust was gone. Some Monday when Brandon called again I did not answer, nor did I answer the 12 times a day they called me for the rest of the week. That saturday I went to make a deposit in the bank and realized I had a balance of negative $316 because they had withdrawl $518.99 from my account on Thursday, I also incurred over $100 in overdraft fees...luckily my bank force paid the checks I had written. I was furious and called the FBI (since I am in Louisianna, I figured it would be interstate fraud) The FBI said they only handle fraud over $15,000. The FBI said I should call the Federal Trade Commission and contact my bank immediately. I have a meeting with the bank on monday to file an affidavit and start a dispute as well as a fraud claim to try and recover my money. I will be filing a report with the FTC when I am done here. I am interested in joining any class action lawsuit, especially because for $600.00 it is not worth it for me to go to a lawyer. I don't know but I think in my case because it is unauthorized withdrawls from an FDIC institute I may be able to go to the DA here in Lousianna. Catherine New Orleans, Louisiana
