I've been a member of Shell Drivers Club for a long time [I'd guess at around 25 years] and my card - that has to be swiped when you purchase petrol - stopped working properly. So I rang them up and was advised to pick up a new card in a petrol station and register it online - from there the new card's number could be transferred to my account.
So I collected a card, and went to this web page which seemed to offer the link I needed. And when I clicked on the link went to - what seemed to be - the right page.
However [and let's ignore the fact the the 'here' link was not identified as a link until you scroll over it] and I was taken to - regular readers will be ahead of me here - this pageYep ... back where I started. Of course I tried it a few times, but the same result. So I've sent them an email, I'll let you know the response.
