My home loan is debiting from the wrong Account

My home loan is debiting from the wrong Account. When applying for the home loan i have provided my banking details and indicated that they debit on the 20th,to my surprise on the banking App it was showing the 25th and i made contact with them serveral times to change the date and they could not help me. Now they are debiting from my husband's Account where as the loan is appearing under my profile and is even appearing under my banking App. I am so ****ed off with your service aready yet i have 239 more months with you. To be honest i wish it was possible to just cancel the whole thing since you cant get the simple things right
