The item no. 3 &4 is last year payment and it had been paid. Otherwise we won't be able to access the EDI customs web access until today if there is any outstanding with them. Regarding the receipt that you request. I also have no idea who pay this to the customs, it might be paid by cash by my team or our customs broker and however all customs receipts that already paid I'm sure that either my team or F/F already provided it to your team. It's a very long time ago and difficult to dig down the detail.
I'd suggest if you can track it from the CBS system base on the payment amount if it was requested as per my above adv.
1) if my team advance cash to pay to the customs, then when we request reimbursement, it would be under my name but if it's CRTT pls track under Kh.Phapawin, You can track all data in CBS payment request so far if your team have put it in.
2) if pay by our customs broker, Schenker or Yusen but likely would be Schenker. You can track from CBS for all invoices from DBS from last year until today.
