Merchants Choice took money out of account with out permission other Texas

Absolutly the worst company EVER, not only did i caught them taking smalll amounts after they had already been paid but they contiued to take out money out of my account even after i had it closed for over a month,when caught the first time they did refund some of my money over $300.00 but contiuen to take it out of account after serviced was cancelled when i called them on it they said oh your are no longer a cliet and sent me to customer service, i had to send them my bank statements to prove it , still haven't heard  aword from them and when i call them now when they know its me they hang up on me!!  I had to block them from ny accounts they were taking money out of 2!! not to mention the fees are insane over 100 a month  and then some little hidden extra 's that you don't notice cause they take it out in small ammounts so unless you really check your accounts every day they got away ith it I am willing to bet they must have ri[[ed me off for thousands of dollars thought the years without me even knowing till i caught them!!! The servoce is the biggest rip off EVER!!! Horrible service ..ripped me off and then refuse to give money back or even call, I i had the money they took illeglly from me I would hire a lawyer..for 3 years they have been ripping me off slowly small amounts but i found out this dec when i had to change my ein number and this crap has dragged on for 4 months it is none ending it has been a NIGHTMARE for me as i am a small busness owner and I cant afford a credit card vender to rip me off like this ...i am at a loss of what to do....I have cried many night over this and it is still not refunded my money yet or return my emails or calls.  One of the WORST EXPEREINCES OF MY LIFE
