Prestige e-mail No Response

Sent an e-mail on 21st July for Prestige banking to contact me, still waiting to hear back from them. First the insurance call back request I made did not get back to me, until I complained & now banking is not responding to the e-mail I sent. I simply cannot sit on the phone all day waiting for somebody to answer on the helpline Why offer the e-mail if nobody is going to respond? The worst thing you ever did was centralise Prestige banking to a call centre and do away with the personal bankers.
