USELESS!!!

I have app**** online for a mobile contract. An agent called me and finalised the application. We made arrangements that the first debit order go off on the 25th of this month, supposedly after 5 days the handset will then be delivered to me. On the 21st, I have received a phone call from the same agent, and yet again we agreed that the debit order go off on the 25th. Today is the 28th and nothing has gone off yet. Yesterday I tried to get through to the call centre on NUMEROUS occassions on the *** number. Today, after NUMEROUS occassions yet again I managed to get through to the 081180 number. Spoke to 2 people, neither could help me. Had to call 10213 spoke again to 2 people. Neither could help me. Told me I have to call *** spoke to a lady that couldn't help me either. So after I have been on the phone for 40 minutes, and spoke to 5 people, nobody could help me!!!! I don't know what's going on with this contract. I am so frustrated and don't know what to do since nobody can help me and I cannot get off work to go to a branch. Online is supposed to make things easier - not harder.
