CAN MY BANK TAKE MONEY FROM MY ACCOUNT FOR AN AMOUNT OUTSTANDING TO THEM WITHOUT MY PERMISSION?

I paid the coupon for over £9000 in to my comment that i’d been sent for profitable nonessential remuneration insurance upon assorted credit cards as well as loan etc. This was an comprehensive God send as i’m carrying critical monetary difficulties as well as programmed to make use of the income to compensate the little debts. On checking my comment once the coupon had privileged i beheld that it was reduction £6000. we called the bank as well as was told that they themselves had taken the volume for an superb credit label check that i had been incompetent to pay. we am positively ravaged during this as we am right away behind to block the single as well as incompetent to compensate any of my debts, the single that would have been the commission of the volume overdue to HSBC. HSBC did this but notifying me. If i’d have well known this was starting to happen, i would have paid the coupon in to an additional account. Can the bank do this or is there the approach i can get the income credited behind in to my comment as well as prepare the befitting re-payment plan?
