Sorry to hear that. Your best option is to call Sonos Sales Support/Customer Care (not Tech Support). They will either replace the unit or send you another power cord. Possibly the latter first. 

However, if you bought it locally, I’d just return the unit. Much quicker turn-around.

Are you pushing it in until it is flush with the socket? It has to be fully inserted to work properly.
