Customer service is a joke, I never got my billing fir the last 2 months and the low tier customer service rep started saying that its my fault since they never received a return to sender and I should check my mailing address, strange since everyone else that has my address has zero problems sending me stuff, not that it's even required since they do everything electronically. The phone reps also told me they will email me the statement which I have yet to receive so I guess I'm gonna have to call these losers again to do their job. God forbid they have to lift a finger to do something
