I'm glad you got it sorted, Nailedit.
It reminds me a bit of when I wanted to pay an Ofcom invoice last year. The email it came with provided a link but it didn't seem to work. So I logged into my Ofcom account and looked to see if the invoice was shown there. It wasn't.
When I phoned Ofcom about it, I was told that they knew that the link that they were sending out in their automatically-generated emails was wrong, as it had been for years, but they couldn't get anybody to fix it! Once I'd been given the correct link, I was able to send the payment with just a few clicks.
