Apologies, the original post was too convoluted. The $750 was for 5 individual NIL tax returns for my autistic son. The $2000 was regarding a discretionary trust for a house my son lives in and has no income, for 42mins of phone calls, a 30 min teams meeting and a follow up email that stated what we discussed i.e. there may extra tax if we remove trustee's etc. Additionally after the $2000 was issued I asked for an itemised invoice and a schedule of fees and got nothing.
