What address do they have for the account? What name were the accounts issued in? Did the debt appear on the liquidators Estimated Statement of Affairs prepared at the time of the liquidation?
If they have a record of it being in if Orange have accepted it was a business account then EE can't pursue you as an individual. This is contradictory. A transfer of ownership would appear to be an isn't all issue for them. I would contact the liquidator to see if this was dealt with during the liquidation process but I would say that this latest email is an admission on their part that it was treated as a business account. I hope that helps. Please leave a positive rating so that I am creditd for my time.
