Welcome to TPG Community!
I was able to pull up an account using your email address.
I've seen that this case is being handled by our Engineering team. I'll chase this up with them and have someone to call you within the day to check the connection using the loan modem.
I understand that you were able to speak with one of our Tech team and was informed that our Engineers already escalated the case to the NBN Co. for further investigation as the service is still dropping out. They are waiting for the response from NBN Co. and once they received an update, they will contact you right away. Thank you for your patience.,
