@Thrall
The link I supplied was, as I said, provided on these forums by a Plusnet staffer. At that time I used it to check that it worked and then bookmarked it. It took me to exactly the same page that the second link in your post now does. I shall now bookmark your link for future use as that accesses both questions and service notices., Thank you. Hopefully Plusnet will not disable that link in the future.
The first link you provide is fine provided you know which question you want to get to. However, Plusnet have a habit of opening then closing questions and it can be useful to peruse your account just to see what is happening especially if unexplained things occur. For instance, I have, in the past, checked for a closed ticket to verify that a recontract offer (sent mid contract) did actually originate from Plusnet and was not a scam. I have also checked for closed tickets whenever there are impending contract changes etc., on my account. Past questions and Service Notices provide a record of what has been done on an account.
However, whilst it is useful to have such a link, only some of those customers who use these forums will be aware of it. The main point I make is that the link to Questions and Service Notices should never have been removed from the Manage Account page of the Members Centre and thus should be readily available to all customers. That change was made a few months ago. The link only allows customers to view existing open and closed questions and service notices but does not permit new tickets to be generated by customers. What is wrong with allowing customers to see and access the definitive record of occurrences on their account? Plusnet should restore that link
