GW deletion – old card

I had a Lane Bryant credit card that I had inadvertently missed a payment on (it actually completely slipped my mind that I had a balance – I was paying in full), in June 2008.  I had 3 TLs on my CRs from them – since my card has been with 3 different banks since it was started.  The derogatory was with the previous bank.  I GW’d the bank that had the card, sent a hard copy GW letter to another address I found for that bank, and I emailed the store through PFB.  Now all three TLs are deleted, at least from Equifax – can I assume that a) my current, open credit card is now non-existent and b) that the deletion came from the store, hence all three TLs gone?  (this didn’t really adversely affect my AAoA, fortunately!)
