Worst home loans department

I have never experienced such bad service in a financial service provider. Opening a query after being sent from bank branch to landline number to a email address and no one assists. Finally after a month getting a reference number. Then after two weeks i received the message the call has been resolved and someone will contact you. No further word after three days as on your side it is closed. I need my debit order stopped immediately as i have gone through all the correct procedures and demand assistance.
