Unauthorized debit order

I am so sick and tired of companies that allow debit orders from your account and if you enquire about it they ask you personal details like what is the daily cash withdrawal limit on your account. I have never withdrawn cash on this account??? I want to know who debit by account on a monthly basis. That's all. <br> No I have to go to a branch because I do not know the daily limit? Well I will anyway go into branch and close my cheque account as well.
