Fed up with Canada Computers - what are my options?

I ordered a CPU/MOBO/RAM bundle from Canada Computers Nov.25th. On Dec.6th they finally sent a waybill for UPS, however UPS shows this package has not yet been received.

I have spent so many hours calling Canada Computers shitty customer service only to be told it's out of their control and I have no options but to wait. They won't even cancel the order and refund me.

I will never do business with this company again. What are my options here?
