Investigative Services Ripped off my bank account and is now threatening Collection Millersville Maryland

I was ripped off By Investigative Services just like many others and found a course of action on your Web page. I contacted the bank and was able to stop the repetitive charges to my bank account just like you advised and was able to get them to refund my money. Now, I am being threatened with Collection proceedings from this same company. I still have yet to ever get a description of any services provided, only a list of continuous attempted charges made to a bank account that has been closed and returned check charges that they are incuring. My list of charges that they are trying to collect have been double charges and provide no details as to what they are for. I have been provided no direct contact name or number with which to attempt to resolve this matter, only the same number (866-863-1005) that goes straight to a recording that no one ever returns a call from. Does anyone have any ideas how to proceed? Can these people trash my credit by going to a collection agency and is there any way to prevent this? P.S. I did however finally get their Virginia License # (11-1526). I wish there was a way to warn the entire public about these people and their shady practices before they too get Ripped Off like me.
