The worst customer experience I have ever experienced in my life.

I was first forced to upgrade my plan for valued added service which I already receive through my car insurance company. Then tried to cancel the upgrade, but was almost effective immediately. But trying to cancel or downgrade my plan has taken 4 months. When I tried to downgrade my plan for a third time, they keep saying that their accounts department only makes changes at the end of today. So I finally receive an email from them at 4:30, only to be told that my whole contract has been cancelled. When I tried to phone to find out why, but the cancellation department only works until 4:30. Maybe this cancellation is a blessing disguise.
