Recurring billing on a closed Account

I have a complaint with Tracker ref ***, account was closed in Feb 2015 and settlement amount paid, proof of account sent and i received confirmation that account is settled and closed, for the past 2 months i have am still getting debited for this account, i have done follow ups with Tracker and received reference numbers and was told they looking into it however no one comes back to me with feedback, i have asked for proof ITC record updated and to date i have not received anything. I keep going to my issuing bank to reverse the debit orders and this is not healthy for my account record, this morning again i have been told they will reverse and they never come back to me until i make the first attempt
