Please provide more information. What is the 0870 number? Do you have a definite company name and address? Check the policy booklet/terms and conditions.

Is this a service where you register your card details with them and should they get lost or stolen, you only have to contact them and they will then contact each card issuer on your behalf? I suspect that this is provided by Card Protection Plan (CPP). Can you tell me whether I'm right?

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

Information about the sale of Marks & Spencer Money to HSBC can be found here. In the case of Card Safe, HSBC uses CPP to provide the service. This is, presumably, a decision that HSBC made and nothing to do with M&S.

 Success!!!!!  I have used  01904 544 685  and got straight through to M & S Card Safe with it.  I spoke with a very pleasant person, no queueing on a line, so maybe it was a quiet time of day.  Thanks.
