Statement charges. Again.

Once again standard bank have managed to charge me for statements on an account that I specifically requested the statements to be sent via email. I laid a complaint on hello Peter for BOTH my standard bank accounts statement fees last month. Was contacted by their representative and was told that both accounts held with standard would be changed to ensure that no statement fees would be charged. The cheque account has been changed and I have not been charged. Yet the market link remains to be charged for statements. How many times does a person have to complain about the same thing before it gets done right?
