level ventures.com I can't explain it , but what a scam they have going Internet

Charges showed up on my checking account for 49.97 and I had no idea what they were for. So I contacted the bank and they took them off but because of the charge I was assed a 35.00 ODC. When I spoke with the bank I was told that the charges came from Level Ventures LTD. and that they would take them off but I still needed to contact the company that put the charges there to start with. I did , when I spoke with them they first told me that their company didn't have a name and they did billing for 1000's of different comapnies.  I had to call back a second time to even have them give me a name. They had half of my email address and somehow had gotten my check card number. I have no idea how this happened. But it did, I honest thought this would never happen to me, but it has so I just want to make sur that they are somehow stopped. This is crazy that they can just charge me and if I hadn't been charged the nsf charge I might not have noticed it. In this computer age I guess it is now more important than ever for us to monitar all charges that post on our accounts. Good luck to anyone that happens to have to deal with this company and there deceptive practices....
