Please acknowledge emails. I sent through an instruction this morning and received no acknowledgement that it has been received. I sent enquiries about a month ago and never received an acknowledgement or a reply - I had to eventually phone the call centre. <br> I object to having to call the call centre to hear whether an instruction has been received - like everyone else my time is limited and I will have to then answer all sorts of inane \security questions"before being able ask whether my instruction has been received. A simply automated response will solve all of this. """
