Pre-contract docs approved but no contract or delivery?

 I've seen a few older discussions on the same issue. I ordered a new broadband connection on the 27th July, due to be delivered for self install on 2nd August. Since then, nothing has happened... I have the order confirmation email, but no contract and no attempt was made to deliver router. 

Early I visited an O2 / Virgin shop to try and see what the issue is. The assistant said she couldn't find my order and that nothing was showing up on the system. She has just setup a new contract for me, which has triggered the exact same emails and documents that I already had from last week. I'm now worried I have two contracts. Additionally, she's input the wrong date for the setup kit to be delivered for this one.

If anyone from Virgin could help or point me in the right direction please. I tried calling the customer care service last week but without an account number (that I don't have without the contract) I can't get through to anyone
