Dear Cingular Wireless,
Since you guys changed my cell-phone plan from original family plan to more expansive plan without any notice, we decided to switch to another service provider. Bye-bye, 再見, さようなら, au revoir, ciao, Auf Wiedersehen, 안녕, adiós, vaarwel, you guys did a good job in the first 10 months.
Sincerely yours.
And….
Hello, T-Mobile!
