Limeroad — Paid for my order but delivery guy said not paid and returned back.

I have paid for my order number. [protected]. But now the delivery guy came and asking payment due. and I showed him the paid details. he said talk to Limroad .. we Are Amazon. and returned back.. It seems Limroad asked me to pay online for Hassel free delivery and now see here I'm tying my issues and no contact number to call.
