Clearwire Wireless Broadband unauthorized duplicate charges, refused to stop charges on my bank account. Internet

In May of 2009, I contacted Clearwire and asked them to stop charging my account. They did not. They didn't even allow me to stop the service, despite my contract being out. (I was under no contract, having already fulfilled one two year contract and not agreed to another one)

They caused my bank account to overdraw, causing me problems. I optimistically waited a while to see if they'd stop. By July, they hadn't stopped attempting.

That being said, I closed the account in Mid-July after having the bank investigate.  The bank was not helpful at all. So I filed a complaint with the BBB in August:

After some back and forth, they essentially refused to settle.
