@Shaneso, now when I am in, I am trying to make a pyament by using "Make a payment" link in the top left corner and I am getting "An existing payment transaction is in progress." Yeah, that's the same message I received the day before the Other Services link broke, when all the fields for updating my details were locked. Ridiculous really. Had to change the payment details by calling 131423. ... View more

It sounds like the same thing happened to you as happened to me. Try the following: Go to TPG's reset password page: https://account.tpg.com.au/reset-password I think I entered the phone number in the first field on that page because the customer ID didn't work. Try one or the other. Reset the password. Go to the usual TPG login page. Enter your phone number and new password. TPG still needs to fix the 'Click here to manage your other services' button or remove it entirely. It seems that changes made to the account details of those 'other services' can break the legacy auto-log in. The user suddenly gets shut out from their mobile account employing a method that had always worked previously and wonders what's going on. They don't even realise that they've had a separate password for that account for the last 2 years. In my case, the broken linking was caused by my credit card expiring. Edit: Cross post. ...

OK, I've solved this one myself. In November 2021 TPG decoupled my mobile account from my main TPG account. It seems the account details from the main account, including payment options and password, were inherited by the mobile account in the transition process. From this point on the details for these accounts would need to be updated independently. I hadn't given it any attention until a few weeks ago when my credit card expired and I received a message from TPG regarding failed payments for the mobile plan. I tried to update the payment details using 'Click here to manage your other services'. Initially, I could access the mobile dashboard, but all the fields were locked with a 'payment processing' message. A day later I was completely shut out and received the same message as the OP. I updated my billing details by calling 131423. Two weeks later I was still locked out of the mobile dashboard.   I figure the mobile account was using an old password imported from the main account in 2021. Never noticed before because the 'Click here to manage your other services' from the main TPG account always worked. Went to TPG's password reset page and changed the mobile account password. The 'other services' button is still broken, but I can now log in directly to the mobile account from TPG's main login page. ... View more

Getting the exact same problem as the OP as of 2 weeks ago. I normally accessed my mobile plan using 'Click here to manage your other services' from the main TPG login. I only have the one password for TPG and it only works with my TPG Username. That takes me to the 'My Account' page with the now broken 'other services' link. My login is rejected if attempted with that password and the mobile plan customer ID number. ... View more
