Incorrect advertising / misinformed staff

On the RCS website there is a huge banner and info on Self Service and to download the Self Service App which sounded great as I've closed my PO Box due to lack of service from Post Office and I would be able to get email statements and update my details online. <br> You cant register on the digital profile registration for this service and are told to call the call center.<br> The lady in the call center was adamant RCS don't offer this service due to high ***** levels! Then why advertise it? You can now expect my postal statements to be returned to sender.
