my name is Jingliang Chen. I have been with tpg for 3 years. now I'd like to switch to using 4G mobile phone, so I want to close my tpg account which is going to expire 20 Apr 2018.
Please tell me what shall I do, as simple and quick as possible?
because I am not a English speaker, please reply me via email.
thank you !
(Only if you can talk to me in mandarin, please call me.)
