TPG app does not work. Deleted and i stalled x3. Via website have to put in 6 digit pin despite entering username and password. Very annoying when you just want to check usage. My internet went down with no way of getting # to call them. 24 hrs later it came back on. Found I had used almost all of my data. Rang and was put on hold constantly by a female who had a crying baby in background. After 30 mins she just hung up on me but did confirm TPG had not sent me a notification I'd used 80% of data 6 days previously (a legal requirement). Rang back. 'Supervisor' was very rude. After 2 addition hours on the phone including him telling me he could see by my d.o.b I had been around a long time, (?) he agreed to give me 2Gb extra data and $10 charge would be waived. 3 weeks later it had nit been waived so I had to make yet another call to TPG. Very nice CSR promised $10 would be refunded within 7 working days. I will not hold my breath.
