I sent an on-line bank transfer (see your add for convenient, safe banking – Stuart Gulliver email address

Gillian sent a message to Stuart Gulliver Group CEO, HSBC Holdings PLC – email address that said:
I sent an on-line bank transfer (see your add for convenient, safe banking!) to NZ to pay for airfare in August (£1,500). Not received and had to pay again in Nov to secure ticket. I have asked, emailed, visited local branch, complained, begged for someone to recall my money. Rob of your Customer Care (that's a laugh) Team has ignored requests to call me to update me, let alone tell me when I am going to get my money back. I have had a month of misery, stress and worry in the UK trying to resolve this and now leave the country tomorrow with nothing done and no satisfaction. The only person, amongst a sea of faceless bureaucracy, who has tried to help has been a member of your Norwich branch, but she has not managed to do anything either. Where do I have to go to get something done? Gillian
