equifax alerts

I have a capital 1 card with free id theft protection etc. Just checked my emails as been away and had an email saying there has been changes to my credit account. when I click through there are 7 new credit agreement summaries and 7 deleted credit agreement summaries for this alert. :eek::eek:The new and deleted are the same numbers (they put the last 4 digits on and they match)
I dont currently have accounts with any of them (but I do think they are possibly old accounts I used to have-credit cards mainly, but one o2 account and a mail order one-redcats?)
Do I need to worry? am very confused. the credit cards always get cancelled when I finish them, I never cancelled a debenhams card but they said it had closed when I asked about it as I hadnt used it for ages
Help!
