Woodforest National Bank Merchants Choice Payment Services Terms & Conditions changed without notice The Woodlands, Texas

They changed the Terms & Conditions of our contract without proper notice.  The new Terms & Conditions extended the term of the contract by one year and increased the early termination fee. 

I assume they changed everyone's Terms & Conditions without proper notice as called for by the same Terms & Conditions - perhaps the makings of a good class action lawsuit.

I canceled my contract  by giving proper notice in writing in accordance with the original Terms & Conditions that were part of my contract.

I sent them a letter explaining their mistake to which they never responded. 
They attempted to withdraw the early termination fee from my bank account - I rejected it.
Recently they turned it over for collection - I have contested it.  I have yet to hear from them.
