Get online support
Before cancelling, do you mind if i ask what seems to be your problem and is there anything i can assist you with?
Could you please send me a PM (private message) with your CID (customer identication number) and your mobile phone number so can help with your query.
There is also a new ''TPG Mobile APP'' to help you with various trouble shooting and account issues, via a mobile phone app.
