Bad experience after another regarding delivery

I called FedEx on Wednesday 8 April to enquire about the delivery as I saw on the tracking info that the address was incorrect according to FedEx. I was told the address was incorrect. we re-confirmed the correct address and was told it would be shipped on Thursday. that didn't happen.<br> Called again on Friday to be told the address was incorrect: again. reconfirmed and was told it would be shipped the afternoon. followed up again on Friday afternoon at 16:30, to be told again that the address was incorrect. FedEx confirmed I would have my parcel by 10:00 on Monday 13 April, that clearly hasn't happened either. I seriously don't know what to do anymore to actually get the parcel delivered.
