The website still listed me as being silver and so I emailed the Gold Card centre pointing this out. Although no reply was received by me, when I log in I am now acknowledged as being a Gold Card member.
I am pleased with the final result but the story is disappointing in that no apology has ever been received and despite asking on several occasions for the contact details of a manager or supervisor to whom I could complain no response has ever been given. In the end I wrote 19 emails, 5 faxes, made 3 telephone calls and sent one registered letter. Was it worth all the hassle and all the expense – probably not. However, ask me next time I am in the airline lounge at Rio and the answer is more than likely to be YES !
