Passing the buck

Upgraded x2 phone contracts. One arrived. Unable to get any answers from anybody. Ive phoned x15 times. Transfered to every department and no one can give me an answer. Absolutely rediculous. Promised a call back as it was escalated. Still waiting. Get sarcastic comments from customer services saying the day is not over yet, it will still be delivered. Big surprise NO delivery. Is anyone capable of assisting??
