What a bunch of crap! On the phone support 10 times, the same thing happens. I get quickly put on to an "Account Specialist" - then I stay on hold forever. I waited for upwards of 2 hours each time to get in touch.
I tried to call, again the same thing - "let me put you onto an Account Specialist", and swiftly puts me on hold, again forever.
I've emailed them at email@example.com - I'm sure this goes nowhere either.
I will be cancelling my card, calling bank, and ACCC for the absolutely non-existent customer service.
By emailing to firstname.lastname@example.org, you would have provided a written notice to TPG. Give 30 days for something to happen. If your account keeps getting debited, then you may proceed with your complaints.
