What a waste of time

I initiated a new contract on March 6th. However, when I followed up on March 19th, I was informed that the phone I chose was discontinued. Subsequently, I entered into another contract on March 19th, which was approved. Yet, I am still awaiting the delivery of the phone. Despite calling three times to inquire about the status, all I'm told is that it's at dispatch. When I asked if they could expedite the process, I was informed that there's nothing they can do and that I should contact the courier for updates. How is that for service.I want to cancel the contract but cant must wait for the phone to be delivered.
