My Statements being sent to a public account!

On the 4th of May I first contacted the Premier Banking as it came to my attention that my business account statements are going through to my old work email address, after i'd physically gone to Bedford Gardens Branch in December 2014 to change my details. I got a call from an agent and was assured they would send them to my current and would send me the statements post haste. They sent through my personal account which is not the correct account I need re directed. I've sent an enquiry 3 times with assurance of it being addressed in 1 working day. I've am still waiting for confirmation. This is a breech of trust on their behalf and an invasion of my privacy allowing others to have privy to my account.
