Contract expired over a year ago?

I opened a planet fitness contract in Feb/March 2011, the contract was supposed to expire in March 2014. I sent an email to customer service in June 2014 saying that I want to cancel my contract (not that I'm supposed to cause it expired 4 months prior to that) cause you guys are still deducting the money from my brother's bank account. No one responded to my email and I didn't get any assistance of any sort. It's been over a year since my contract expired but you are still deducting the money after that. PLEASE CANCEL MY CONTRACT IMMEDIATELY. And what happens to all the money that was deducted after the contract expired? Today I received an SMS saying that my contract is in arrears. Please sort this out immediately. I don't even use my contract anymore seeing that the branch I used burned down like 2 years ago. Just sort this out.
