About customer ID

Level 2
I took over TPG wifi from previous tenant
5years ago . At that time, I registerd my name , email and other detail on the phone.
But I haven’t got any bill, email from TPG so far
and still don’t know my customer ID
TPG just takes money by direct debit.
I give you my detail.
1) Can you plz check and
2) let me know my customer ID
3) send me the bill via email
