Online purchase delays after paying for express

I ordered a dress on Saturday the 27th Jan and selected to pay an additional fee for express delivery. On the 31st Jan I call the call centre to follow up as the package should have arrived already. Firstly the call took 8 minutes to determine that the package was not at the store yet (useless information) and then only informed me that it will be delivered by the 1st of Feb. On the afternoon of the 1st I call and this call took 14 minutes to determine that the package did not arrive yet (these are clearly not rocket scientists). This time I am told the package will only arrive by Monday the 5th Feb??? total of 10 days after paying for 3 express delivery?!?!?!?!?!?! This is appalling! The call centre agents don't care to help you get things resolved. The online chat person is probably chatting to someone on her cellphone because she is clearly taking forever to respond to me. I am completely done with Mr P(athetic) . I will rather spend my money at a store that values customers enough to stick to their set expectations.
