Courier not responding

UPS sent me certificate showing pkg. delivered to Miami 2 weeks ago as Courier agreed. And as usual, Courier is demanding deposit to her account at local bank before usual delivery by Servientrega, but has not provided her usual email invoice showing bank deposit info and amount to pay. I paid $175 for contents because I urgently need it. I have messaged Courier many times for invoice for bank pmt. but no response from her now. Any kind suggestions as to what to do now? (No nasties, please.)
