Debit order decuctions for the past year after cancelation

My brother cancelled his clientele legal account more than a year ago. And they told him it was cancelled yet you are deducting from him everymonth and sometimes double the amount. After numerous failed communication with clientele legal i feel all the money you have debited since cancelation should be paid back to my brother. He is a quadroplegic and cant afford this. He cant just change his bank account as his workmans comp gets paid into this account forcing him to stay awake until after 12 at night to transfer his funds before you take it. But yet then you change the date and try deduct on different dates. And yet you took again at twelve last night as soon as his salary was paid in. You guys need to refund my brother all that money that you have taken simce cancelation you know the banks cant help nore stop your debit order so i feel its only right that you are fair in doing so amd refunding him. Hes in a wheelchair and needs that money to live its very bad service from a company that is supposed to help people but instead ***** from people
