Allstate Financial Services Took money from checking account at unauthorized time Las Vegas, Nevada

Beware!!!!!!!!!!!!!!  Anyone that is contacted by this company for a bill that is owed, DO NOT give any banking information, they will take money out on dates that have not been authorized by you.  I was contacted by this company for a debt I owe, I made payment arrangements with them.  I was advised by the rep that I spoke to that if the dates we set up did not work, call back and they would change the dates.  Which I ended up having to do due to unforseen circumstances.  I went to get money from my account only to find out my account had insufficient funds.  The company took money out after I had contacted them and changed the date for the withdrawl.  I contacted the company and spoke to a supervisor who was laughing when I was explaining my situation.  When I asked for his name, he laughed again and hung up on me.  Very unprofessional in my opinion. After more agonizing phone calls to this company, I was able to speak to the project manager, and the situation was resolved.  I will never give any banking information to this or any company again.  From now on, everything will be done with money orders.
