That is the address for CPP (look at its website). I don't think that it has any connection to HSBC, although I may be wrong. I searched the CPP site for HSBC and nothing came up. They provide cover to Barclays customers under the name
Barclays Cardholder Protection, the thread for which is
here. I doubt that HSBC would provide services for rival banks.
I wrote have a CardGuard account which is the HSBC branded one. I wrote and complained and was told that they do not have geographical numbers. Quite obviously they are blatent liars as I found one to the York office on an old credit card statement. This number still works.
I believe that the customer services for Marks & Spencer branded accounts can be contacted on
01904 544685. Please let me know if I'm correct. I have used this in the past for enquiries about my HSBC policy, so if it doesn't work, try any of them. Search the database for CPP and some alternatives will come up.
Details of the management can be found
here. I e-mailed Dianne Cheesebrough a while ago, but she didn't reply to me. Neil Hamilton, Group IT Director might be worth a go. E-mail addresses are of the form firstname.lastname@cpp.co.uk
