Where to start: Here are some examples of Barclays failures. Failed to update mandates twice Refused a signature because it was too small despite it having to be confined in a small box on a form. Failed to send deposit forms ordered on web site after phone call sent 5 books of forms. Allowed access to an account without it being requested. Started applying charges to an account which had been charge free without informing the customer. Refused a cheque when a customer was in the process of changing branches. Unintelligible call handlers All these problems involve the same customer.
